I reran the 2.6.0-test6-mm4 benchmarks and it still is much slower than the the 2.4.23. Question for Jason: -- are you running the 4/4 vm layout in your kernel? My 2.6.0-test6-mm4 has the 4/4 vm enabled -- which can have an impact on performance. I'll tetest with 2.6.0-test9 without the mm1 and 4/4 vm enabled. eric Linux host 2.4.23-rc1 #2 SMP Thu Nov 13 11:30:02 MST 2003 i686 athlon i386 GNU/Linux /test> bonnie -s 100 Writing with putc()... done: 9228 kB/s 52.0 %CPU Rewriting... done: 9435 kB/s 6.0 %CPU Writing intelligently...done: 9235 kB/s 4.0 %CPU /test> rm file;time dd if=/dev/zero of=file bs=1 count=10000000 10000000+0 records in 10000000+0 records out real 0m20.086s user 0m3.120s sys 0m16.740s ------------------------------------------------------- This SF.Net email sponsored by: ApacheCon 2003, 16-19 November in Las Vegas.
