Assesses the performance of the processor(s) using encryption and decryption or compression and decompression.
For examples of how to use this command, see Examples.
Syntax
winsat cpu <[encryption|encryption2]|[compression|compression2]> [optional parameters]
Parameters
|
Important |
|
Only one of the four required parameters is required to run the assessment. |
| Required Parameter | Description |
|---|---|
|
-encryption |
Run the encryption and decryption sub-assessment using 256-bit AES cryptographic algorithms. |
|
-encryption2 |
Run the encryption and decryption sub-assessment computing a SHA1 hash. |
|
-compression |
Run the compression and decompression sub-assessment using a Lempel-Zev algorithm. |
|
-compression2 |
Run the compression and decompression sub-assessment using an internal Microsoft compression algorithm. This is the same algorithm used to compress the hibernation file and with ReadyBoost and ReadyDrive technologies. |
| Optional Parameter | Description |
|---|---|
|
-buffersize <n> |
Define the buffer size for the assessment. The minimum is 4K. The maximum is 2MB. The default is 16KB. |
|
-data <file name> |
Specify a file to be loaded into the buffer for use in the assessment. The default file used if none is specified is %SystemRoot%\system32\shell32.dll. |
|
-nbr <n> |
Specify the number of buffer regions used in the assessment. The default is 16 regions. |
|
-brs <n> |
Specify the size of buffer regions used in the assessment. |
|
-v |
Send verbose output to STDOUT, including status and progress information. Any errors will also be written to the command window. |
|
-xml <file name> |
Save the output of the assessment as the specified XML file. If the specified file exists, it will be overwritten. |
|
-idiskinfo |
Save information about physical volumes and logical disks as part of the <SystemConfig> section in the XML output. |
|
-iguid |
Create a globally unique identifier (GUID) in the XML output file. |
|
-note "note text" |
Add the note text to the <note> section in the XML output file. |
|
-icn |
Include the local computer name in the XML output file. |
|
-eef |
Enumerate extra system information in the XML output file. |
|
Note |
|
A combination of -buffersize, -nbr, and -brs can be specified, but only two can be used simultaneously. |
- When -buffersize and -nbr are used together, the
region size is determined by dividing the number of regions into
the buffer sizes.
- When -buffersize and -brs are used together, the
number of regions is determined by dividing the region size into
the buffer sizes.
- When -nbr and -brs are used together, the buffer
size is determined by multiplying the values for -nbr and
-brs together.
Additional considerations
The -buffersize value defaults to bytes unless a suffix is used with the number supplied. The following suffixes can be used to specify other magnitudes:
- B or BYTES for bytes (assessments that do not permit values
this small will default to the smallest allowed value)
- K or KB for kilobytes
- M or MB for megabytes
- G or GB for gigabytes (assessments that do not permit values
this large will default to the largest allowed value)
Examples:
- -buffersize 1K
- -buffersize 256BYTES
Examples
- The following example assesses CPU performance using 256-bit
AES cryptographic algorithms:
winsat cpu -encryption
- The following example assesses CPU performance using the same
compression algorithms that Windows Vista uses internally:
winsat cpu -compression2
Remarks
- Membership in the local Administrators group, or equivalent, is
the minimum required to use winsat. The command must be
executed from an elevated command prompt window.
- To open an elevated command prompt window, click Start,
click All Programs, click Accessories, right-click
Command Prompt, and click Run as administrator.
