Appendix: Performance Test Tool (perfsys) Command Line Options

Intel® Integrated Performance Primitives (Intel® IPP Cryptography) 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 IPP Cryptography functions. The
ps_crypto_mb
executable measures performance for all Intel IPP Multi-buffer Cryptography functions. Note that
ps_crypto_mb
executable can be ran on 3rd Gen Intel® Xeon® Scalable processors only.
Many factors may affect Intel IPP Cryptography 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 IPP Cryptography 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:
