Understanding Performance Tab of Windows Task Manager

Many time we feel measuring performance of application manually is bit difficult, but in real sense it is not. There could be many possible ways to measure performance of application manually but the technique I am going to explain here is bit easy and handy.

If we have Windows OS then we can open Task manager (Right Click on Windows Task Bar and click on Task manager or press ALT+CTRL+DEL key and click on Task manager) and Open performance TAB, as shown in picture below -


The Performance tab displays a dynamic overview of your computer's performance. Click one of the following for more information:

CPU Usage

A graph indicating the percentage of time the processor is working. This counter is a primary indicator of processor activity. View this graph to see how much processing time you are using. If your computer seems to be running slowly, this graph could display a higher percentage.

CPU Usage History

A graph showing how busy the CPU has been over time. The sampling displayed in the graph depends on the value you select for the Update Speed on the View menu. Updates occur with these possible values: High = twice per second; Normal = once every two seconds; Low = once every four seconds; Paused = display doesn't automatically update.

PF Usage

The amount of paging file being used by the system. If your computer is running near the maximum, you can increase the page file size.

Page File Usage History

Graph depicting the amount of page file used over time. The sampling displayed in the graph depends on the value you select for the Update Speed on the View menu.

Totals

Totals for the number of handles, threads, and processes running on the computer.

Commit Charge (K)

Memory allocated to programs and the operating system. Because of memory copied to the paging file, called virtual memory, the value listed under Peak may exceed the maximum physical memory. The value for Total is the same as that depicted in the Page File Usage History graph.

Physical Memory (K)

The total physical memory, also called RAM, installed on your computer. Available represents the amount of free memory that is available for use. The System Cache shows the current physical memory used to map pages of open files.

Kernel Memory (K)

Memory used by the operating system kernel and device drivers. Paged is memory that can be copied to the paging file, thereby freeing the physical memory. The physical memory can then be used by the operating system. Nonpaged is memory that remains resident in physical memory and will not be copied out to the paging file.

However, if you click on View->Show Kernel Times you can get information about the CPU Usage Time on the System (Kernel).


The Red Line displays Kernel CPU usage, while the Green Line displays total CPU usage.

This means that if your trying to figure out how much CPU your current program is using you take the Green (Total) CPU Usage - Red (System) CPU Usage = Current Application Usage.

Also if you Double Click on the Graph it will display in the full window.

Double Click the graph to go back to the previous view

To check how much CPU a Perticular process (you shall know the name of the process you application runs) is taking you can siply open the Processes TAB


Here you can check User vise list of processes running at a perticular time and can also check how much CPU Usage, CPU time and Memory Usage a perticular Process is taking, not only this there are many other columns which can be added in this view.

You can configure which columns are displayed (View->Select Columns), and rearrange their order by dragging the column headers in the usual way. On XP, you can decide whether to show other user's processes or just your own.

Click on View -> Select Column...

and check/unchecked the column names you want to see in the view -


The 'image name' is the name of the executable file used when the process was created; this name is popularly referred to as the name of the process, though it's not really. (Why 'image'? Because programmers used the word 'image' for 'memory image file' long before it was possible to put pictures on a computer without a defense-department-sized budget).

There are two exceptions to this, the System Idle Process (pid 0) and the System process (pid 4). These are wired into the kernel, and do not have corresponding image files. They don't have image names either, so various tools such as Task Manager make up names, so you might see different names in different tools.

The System Idle Process consumes all the CPU time that no-one else wants. If no other process is ready to run (on a particular CPU), the kernel will run the idle process.

The System process contains threads used by the OS kernel for 'background' functions. For example, the working set trimmer, which may reclaim physical memory from some processes, runs as a thread in the System process. The System process may also have threads used by some device drivers to do work outside the normal path of operation. (If the System process is using a huge amount of CPU for an extended time, it usually means some device driver is to blame).

Most of the columns of data are adequately explained by Task Manager's help, so I won't repeat the information here. The memory-related data, however, could probably use extra clarification.

The Mem Usage column shows the current working set size for the process, which is to say, the amount of physical memory the process is currently allocated. Three things need to be said here: firstly, this is only somewhat related to "how big the process is". The process is probably larger than that; the OS's job is to keep only those pages in physical memory that it is useful to have in physical memory. Secondly, the number can get smaller, if the OS decides to take some physical memory away from the process ('working set trimming'), which it will do if it has some other use for the memory. Lastly, you can't add up all the numbers and get the total used by all processes; some of the physical memory is shared by more than one process.

The VM Size column shows the number of Private Bytes of virtual memory owned by the process. As always, 'virtual memory' does not necessarily mean disk or RAM; it could be either, or neither.

Further notable aspects of Task Manager:

PID.

The Process ID (PID) is listed next to the process, allowing you to execute the KILL command at the command line to terminate an out-of-control process. Of course you can more easily accomplish the same thing by clicking the End Process button.

Set Priority.

Right-clicking a process and selecting Set Priority allows you to set the processing priority for the process from Real time to Low.

Set Affinity.

By default, activity is distributed over multiple processors in Windows 2000 without any involvement from you. This is a technique known as Symmetrical Multiprocessing (SMP). However, you can assign a process to a specific processor by selecting the Set Affinity menu option displayed on the secondary menu when you right click a process. This allows you to invoke Asymmetrical Multiprocessing just like the good old mainframe days.

Customize.

Choosing Select Columns on the View menu when the Processes tab is displayed in Task Manager allows you to select many more reporting columns (As Show in Above Pictures). If you click OK, the Processes tab reflects many more columns of information.

Process Area (CMMi and KPA's)

Before Proceeding further, we need to understand CMMi terminology first please have a glance at the following table –

Concept

Definition

AMPLIFICATION

Amplifications are informative model components that contain information relevant to a particular discipline. For example, to find amplification for software engineering, one would look in the model for items labeled “For Software Engineering.” The same is true for other disciplines.

CAPABILITY LEVEL

Achievement of process improvement within an individual process area. A capability level is defined by the appropriate specific and generic practices for a process area.

CMMI MODEL

A model generated from the CMMI Framework.

CONTINUOUS REPRESENTATION

A capability maturity model structure wherein capability levels provide a recommended order for approaching process improvement within each specified process area.

GENERIC GOAL

A required model component that describes characteristics that must be present to institutionalize processes that implement a process area.

GENERIC PRACTICE

An expected model component that is considered important in achieving the associated generic goal. The generic practices associated with a generic goal describe the activities that are expected to result in achievement of the generic goal and contribute to the institutionalization of the processes associated with a process area.

GENERIC PRACTICE ELABORATIONS

An informative model component that appears after a generic practice to provide guidance on how the generic practice should be applied to the process area.

GOAL

A required CMMI component that can be either a generic goal or a specific goal. The word goal in a CMMI model always refers to a model component (e.g., generic goal and specific goal).

MATURITY LEVEL

Degree of process improvement across a predefined set of process areas in which all goals in the set are attained.

PROCESS AREA

A cluster of related practices in an area that, when implemented collectively, satisfies a set of goals considered important for making improvement in that area. All CMMI process areas are common to both continuous and staged representations.

REFERENCE

An informative model component that points to additional or more detailed information in related process areas.

SPECIFIC GOAL

A required model component that describes the unique characteristics that must be present to satisfy the process area.

SPECIFIC PRACTICE

An expected model component that is considered important in achieving the associated specific goal. The specific practices describe the activities expected to result in achievement of the specific goals of a process area.

STAGED REPRESENTATION

A model structure wherein attaining the goals of a set of process areas establishes a maturity level; each level builds a foundation for subsequent levels.

SUBPRACTICE

An informative model component that provides guidance for interpreting and implementing specific or generic practices. Subpractices may be worded as if prescriptive, but they are actually meant only to provide ideas that may be useful for process improvement.

WORK PRODUCT

In the CMMI Product Suite, a useful result of a process. This can include files, documents, products, parts of a product, services, process descriptions, specifications, and invoices. A key distinction between a work product and a product component is that a work product is not necessarily part of the end product.

All CMMI models contain multiple process areas (PAs). A PA has 1 to 4 goals, and each goal is comprised of practices. These goals and practices are called specific goals and practices, as they describe activities that are specific to a single process area. An additional set of goals and practices applies across all of the process areas; this set is called generic goals and practices.

The latest version of Capability Maturity Model Integration (CMMi) is Version 1.2 which contains 22 process areas(as Listed Below) that describe the aspects of product development that are to be covered by organizational processes.

  • Causal Analysis and Resolution
  • Configuration Management
  • Decision Analysis and Resolution
  • Integrated Project Management
  • Measurement and Analysis
  • Organizational Innovation and Deployment
  • Organizational Process Definition
  • Organizational Process Focus
  • Organizational Process Performance
  • Organizational Training
  • Project Monitoring and Control
  • Project Planning
  • Process and Product Quality Assurance
  • Product Integration
  • Quantitative Project Management
  • Requirements Management
  • Requirements Development
  • Risk Management
  • Supplier Agreement Management
  • Technical Solution
  • Validation
  • Verification

Process Area Categories

There are four process area categories used in CMMI for Development: Project Management, Process Management, Engineering, and Support.

Process Management

  • OID - Organizational Innovation and Deployment
  • OPD - Organizational Process Definition +IPPD
  • OPF - Organizational Process Focus
  • OPP - Organizational Process Performance
  • OT - Organizational Training

Project Management

  • PP - Project Planning
  • PMC - Project Monitoring and Control
  • SAM - Supplier Agreement Management
  • IPM - Integrated Project Management +IPPD
  • RSKM - Risk Management
  • QPM - Quantitative Project Management

Engineering

  • REQM - Requirements Management
  • RD - Requirements Development
  • TS - Technical Solution
  • PI - Product Integration
  • VER - Verification
  • VAL – Validation

Support

  • CM - Configuration Management
  • PPQA - Process and Product Quality Assurance
  • MA - Measurement and Analysis
  • DAR - Decision Analysis and Resolution
  • CAR - Causal Analysis and Resolution

Maturity Levels

There are five maturity levels. However, maturity level ratings are awarded for levels 2 through 5.

Maturity Level 1 - Ad hoc (Chaotic)

It is characteristic of processes at this level that they are (typically) undocumented and in a state of dynamic change, tending to be driven in an ad hoc, uncontrolled and reactive manner by users or events. This provides a chaotic or unstable environment for the processes.

This Level does not have any KPA linked with it.

Maturity Level 2 – Repeatable

It is characteristic of processes at this level that some processes are repeatable, possibly with consistent results. The processes may not repeat for all the projects in the organization. The organization may use some basic project management to track cost and schedule.

Process discipline is unlikely to be rigorous, but where it exists it may help to ensure that existing practices are retained during times of stress. When these practices are in place, projects are performed and managed according to their documented plans.

Following are the KPA’s linked to this level

  • CM - Configuration Management
  • MA - Measurement and Analysis
  • PMC - Project Monitoring and Control
  • PP - Project Planning
  • PPQA - Process and Product Quality Assurance
  • REQM - Requirements Management
  • SAM - Supplier Agreement Management

Maturity Level 3 – Defined

It is characteristic of processes at this level that there are sets of defined and documented standard processes established and subject to some degree of improvement over time. These standard processes are in place (i.e., they are the AS-IS processes) and used to establish consistency of process performance across the organization. Projects establish their defined processes by applying the organization’s set of standard processes, tailored, if necessary, within similarly standardized guidelines.

Following are the KPA’s linked to this level

  • DAR - Decision Analysis and Resolution
  • IPM - Integrated Project Management +IPPD
  • OPD - Organizational Process Definition +IPPD
  • OPF - Organizational Process Focus
  • OT - Organizational Training
  • PI - Product Integration
  • RD - Requirements Development
  • RSKM - Risk Management
  • TS - Technical Solution
  • VAL - Validation
  • VER – Verification

Maturity Level 4 – Managed

It is characteristic of processes at this level that, using process metrics, management can effectively control the AS-IS process (e.g., for software development ). In particular, management can identify ways to adjust and adapt the process to particular projects without measurable losses of quality or deviations from specifications. Process Capability is established from this level.

Following are the KPA’s linked to this level

  • QPM - Quantitative Project Management
  • OPP - Organizational Process Performance

Maturity Level 5 – Optimized

It is characteristic of processes at this level that the focus is on continually improving process performance through both incremental and innovative technological changes/improvements.

Following are the KPA’s linked to this level

  • CAR - Causal Analysis and Resolution
  • OID - Organizational Innovation and Deployment

Goals and Practices

There are two categories of goals and practices: generic and specific. Specific goals and practices are specific to a process area. Generic goals and practices are a part of every process area. A process area is satisfied when organizational processes cover all of the generic and specific goals and practices for that process area.

Specific Goals and Practices

Each process area is defined by a set of goals and practices. These goals and practices appear only in that process area.

Generic Goals and Practices

Generic goals and practices are a part of every process area.
