Introduction

This command used for measures the performance of the processor using encryption and decryption or compression and decompression.

Syntax

winsat cpu <[encryption|encryption2]|[compression|compression2]> [optional parameters]


 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.
-buffersize <n> Define the buffer size for the assessment. The minimum is 4K. The maximum is 2MB. The default is 16KB.
-nbr <n> Specify the number of buffer regions used in the assessment. The default is 16 regions.
-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.
-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.
-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


Example

This example assesses CPU performance using 256-bit AES cryptographic algorithms:

winsat cpu -encryption

This example assesses CPU performance using the same compression algorithms that Windows Vista uses internally:

winsat cpu -compression2
