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
.gif) 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. |
.gif) 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

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.
