Summary: 2.4.14-pre3aa1 takes more wall time for tests. Audio sounds closer to the "edge", I.E more likely to skitter or skip.
Test: Run "mtest01 -w 80" and mmap001 from LTP. Listen to long mp3 sampled at 128k. Light console irc client and lynx use.
2.4.14-pre3aa1
About 2-3 seconds of sound skitter when typing a URL in lynx or something in irc client.
Averages for 10 mtest01 runs bytes allocated: 1246232576 User time (seconds): 2.105 System time (seconds): 2.773 Elapsed (wall clock) time: 59.503 Percent of CPU this job got: 7.80 Major (requiring I/O) page faults: 132.8 Minor (reclaiming a frame) faults: 305043.1
About 2-3 seconds of sound drop on mmap001 for 2.4.14-pre3aa1.
Average for 5 mmap001 runs bytes allocated: 2048000000 User time (seconds): 19.660 System time (seconds): 16.272 Elapsed (wall clock seconds) time: 287.13 Percent of CPU this job got: 12.00 Major (requiring I/O) page faults: 500168.0 Minor (reclaiming a frame) faults: 38.8
2.4.14-pre3
Same two tests on 2.4.14-pre3 for comparison:
Averages for 10 mtest01 runs bytes allocated: 1233859379 User time (seconds): 2.034 System time (seconds): 3.036 Elapsed (wall clock) time: 30.517 Percent of CPU this job got: 16.10 Major (requiring I/O) page faults: 107.0 Minor (reclaiming a frame) faults: 302029.3
Average for 5 mmap001 runs bytes allocated: 2048000000 User time (seconds): 19.578 System time (seconds): 17.388 Elapsed (wall clock seconds) time: 171.45 Percent of CPU this job got: 21.20 Major (requiring I/O) page faults: 500158.8 Minor (reclaiming a frame) faults: 41.4
