    3 This page shows the CPU requirements/MIPS (Million Instructions Per Second) measurements of various PJMEDIA components which would be useful to evaluate PJMEDIA performance. Please do not interpret these numbers as the official or definite performance number, as there are many compilation flags in PJMEDIA that can be set, as well as compiler switches, to improve the performance.

    5 All the results below are done with the stock settings that come with PJSIP distribution. The test source is in {{{pjmedia/src/test}}} directory.

Please do not interpret these numbers as an official or definite performance number, as these tests do not actually measure the actual number of instructions executed but rather the time, and there are many compilation flags in PJMEDIA as well as compiler switches that can be set to improve the performance.

    75== Test Method == 
     
    119The test program depends on a correct setting of MIPS value of the processor being set correctly during compilation time. The test uses strictly one thread only. 
    1210 
     11To measure the MIPS value of a component, the program calculates the time to process 1 second worth of audio samples using that component, then calculates the MIPS value based on the configured MIPS value of the processor.

     13All the results below are done with the stock settings that come with PJSIP distribution. The test source code is available in '''pjmedia/src/test''' directory ({{{mips_test.c}}} file).
