I haven't tried the patched version of the LTP tests yet. This is with 2.4.14-pre3aa4.
Summary:
mtest01 2.4.14-pre3 Elapsed (wall clock) time: 30.517 2.4.14-pre3aa2 Elapsed (wall clock) time: 65.176 2.4.14-pre3aa4 Elapsed (wall clock) time: 37.277
mmap001 2.4.14-pre3 Elapsed (wall clock seconds) time: 171.45 2.4.14-pre3aa2 terminated with signal 9 2.4.14-pre3aa4 Elapsed (wall clock seconds) time: 170.47
2.4.14-pre3 had the best interactive feel and mp3 sound.
Test: "mtest01 -p 80" -w and "mmap001 -m 500000" Play mp3 sampled at 128k with mp3blaster. Light bitchx use (2 sessions), lynx, 52k link to net. vmstat 8, iostat 10, no X. (typical load for these tests). Change page-cluster from default (3) to 2.
2.4.14pre3aa4 page-cluster=3
mp3 played 275 seconds of 373 second run.
