Performance Test Tool (perfsys) Command Line Options
Intel® Cryptography Primitives Library installation includes a command-line tool for performance testing in the <install_dir>/tools/perfsys directory. The ps_ippcp executable measures performance for all Intel® Cryptography Primitives Library functions. The ps_crypto_mb executable measures performance for all Intel® Cryptography Primitives Library Multi-buffer functions. Note that ps_crypto_mb executable can be ran on 3rd Gen Intel® Xeon® Scalable processors only.
Many factors may affect Intel® Cryptography Primitives Library performance. One of the best way to understand them is to run multiple tests in the specific environment you are targeting for optimization. The purpose of the perfsys tools is to simplify performance experiments and empower developers with useful information to get the best performance from Intel® Cryptography Primitives Library functions.
With the command-line options you can:
Create a list of functions to test
Set parameters for each function
Set image/buffer sizes
To simplify re-running specific tests, you can define the functions and parameters in the initialization file, or enter them directly from the console.
The command-line format is:
ps_ippcp.exe [option_1] [option_2] ... [option_n]
To invoke the short reference for the command-line options, use -? or -h commands:
ps_ippcp.exe -h
The command-line options are divided into several groups by functionality. You can enter options in arbitrary order with at least one space between each option name. Some options (like -r, -R, -o, -O) may be entered several times with different file names, and option -f may be entered several times with different function patterns. For detailed descriptions of the perfsys command-line options see the following table:
