PJMEDIA Performance Measurement
This page attempts to show the typical performance characteristic of various PJMEDIA components, which could be useful to evaluate PJMEDIA performance. Please do not interpret these numbers as an official or definite performance number, as there are many compilation flags in PJMEDIA as well as compiler switches that can be set to increase (or decrease) the performance.
Test Method
Each test should measure the overall performance for both directions. So for example for resampling, the test shows the total upsample and downsample time in a single test, and for codec it will show the total encoding and decoding time.
The test program depends on correct settings of CPU_MHZ and MIPS value of the processor being set correctly during compilation time. We used the MIPS information in the following links to assume the MIPS value of the processor:
- http://en.wikipedia.org/wiki/Million_instructions_per_second
- http://en.wikipedia.org/wiki/ARM_architecture
To measure the MIPS score of a component, the program calculates the time to process 1 second worth of audio samples using that component, then calculates the MIPS score based on the configured MIPS value of the processor. Because of this, the calculated MIPS shouldn't be interpreted as a real MIPS value since it's purely based on time measurement, and our assumed MIPS value for the processor may be wrong.
The test uses strictly one thread only.
All the results below are done with the default settings that come with PJSIP distribution. The test source code are available in pjmedia/src/test directory (mips_test.c file).
Interpreting the Results
Columns
There are four columns in the result table:
- Clock Rate:
- This shows the sampling rate of the component being tested, in KHz. We test both 8KHz and 16KHz. Most components can work in both 8KHz and 16KHz hence there will be two test result rows for the same component, each with different clock rate. Some components (mostly related codec) can only work in one of the clock rate (e.g. GSM is only shown in 8KHz, while G.722 is only shown in 16KHz) hence there will only be one test result row for these components.
- Time (usec):
- This shows the time elapsed to process 1 second worth of audio samples, in microseconds.
- CPU (%):
- This shows how much CPU usage (in percent) this component will consume when running it in real-time. The value is derived from the time measurement above. For example, if the time elapsed is 1 secondthen this component will take 100% of CPU time when run in real-time. Or if the time elapsed is 0.5 second then this component will take 50% of the CPU time when run in real-time.
The CPU percentage maybe larger than 100% if the time taken to process 1 second worth of audio samples is more than 1 second. It may happen when we perform the test on slower processor.
- MIPS:
- The MIPS (Million Instructions per Second) score roughly means how many instructions will be executed by this component per second when we run this component in real-time. The value is derived from the time measurement above, and calculated based on the assumed MIPS value of the processor. Once again, the score may be incorrect for many reasons so it shouldn't be interpreted as an official/definite score, and especially one MUST NOT use the MIPS score to compare performance of different processor families/architectures.
Rows
The rows show the measurement result of a particular components. The components tested are described below.
- get from memplayer:
- The memory/buffer based player port supplies the audio samples for almost all of the tests, so its time adds as overhead for all tests.
- conference bridge with N call(s):
- This measures the performance of the conference bridge with N calls. Note that we don't use actual call for the test since we only want to measure the conference bridge performance and not codec performance (this will be measured in separate tests). So for this test we use memplayer for each "call" to supply audio to the bridge. During the test all the calls (ports) will be connected to port zero and port zero will be connected to all calls. No connection among calls are created.
- upsample+downsample:
- This measures the performance of the resampling algorithm used. The test gets the audio from the memplayer, upsample it twice the clock rate, then downsample it half the clock rate again so that the clock rate now is the same as originally. This test measures both linear and non-linear resampling using small filter and large filter. Some resampling backend algorithms may not support selecting between linear/non-linear and small/large filter, in that case the results will be equal for all settings.
- WSOLA PLC - N% loss:
- This measures the performance of Waveform Similarity based Overlap and Add (WSOLA) algorithm when it is used to generate/emulate lost packet (a.k.a Packet Lost Concealment/PLC). Timing for various loss percentages are shown.
The WSOLA algorithm is used by both the delay buffer and PLC algorithm in pjmedia. The delay buffer itself is used by the splitcomb, sound port, and the conference bridge to adapt to audio burst and clock drifts.
- WSOLA discard N% excess:
- This measures the performance of Waveform Similarity based Overlap and Add (WSOLA) algorithm when it is used to discard excess audio samples (e.g. caused by clock drifts). Timing for various excess percentages are shown.
- echo canceller Nms tail len:
- This measures the performance of the acoustic echo canceller (AEC) for various echo tail settings. The audio source is taken from memplayer, and there is no acoustic delay in the AEC input.
- tone generator with single/dual freq:
- This measures the performance of the tone generator to continuously generate single or dual frequency tone for 1 second.
- codec encode/decode:
- This measures the time to encode and then decode 1 second worth of audio samples using the specified codec for 1 second.
- stream TX/RX:
- This test is intended to measure the performance/overhead of the stream, which consist of codec, RTP/RTCP processing, and de-jitter buffering. In addition it also tests the performance of Secure RTP (SRTP) for various setting combinations and codec bandwidth. Since the test here also consists of codec processing (encoding and decoding), you need to subtract the result with the result of the corresponding codec to measure the overhead of the stream and SRTP only.
