Simultaneously listen to long mp3 sampled at 128k with mp3blaster. Summary: 2.4.15-pre6 49% faster on memfill test with higher mp3 play time. 2.4.15-pre6 11% faster on mmap test. Config diff: CONFIG_RWSEM_XCHGADD_ALGORITHM=y in 2.4.15-pre6 Hardware: Athlon 1333 1024 MB RAM 1024 MB swap 2.4.15-pre6 used a higher percentage of CPU time for both tests. 2.4.15-pre6 played 97% of mp3 and 2.4.15pre6aa1 played 84% during memfill test. I include one iteration of vmstat 1 from the memfill test because of differences in b, free, memcache, etc columns. 2.4.15-pre6 ------------- mp3 played 297 seconds of 304 second run.
