A couple of things I have noticed in the kernel messages: WARNING: WITNESS option enabled, expect reduced performance. You need to remove the WITNESS and the INVARIANTS options from your kernel when benchmarking. ad0: DMA limited to UDMA33, controller found non-ATA66 cable ad0: 28629MB <Seagate ST330630A 3.17> at ata0-master UDMA33 ad1: DMA limited to UDMA33, controller found non-ATA66 cable ad1: 28629MB <Seagate ST330630A 3.17> at ata0-slave UDMA33 ad3: 38166MB <Seagate ST340810A 3.99> at ata1-slave UDMA100 You need to use the 80 core conductor cables instead of the old standard 40 core conductor IDE cables to get the best performance from your hard drives. Just use another cable like you already have connected to the 40GB drive. -----Original Message----- From: owner-freebsd-current@freebsd.org [mailto:owner-freebsd-current@freebsd.org] On Behalf Of Ganbold Sent: Thursday, 30 March 2006 4:55 PM To: freebsd-current@freebsd.org Cc: jasone@freebsd.org; deischen@freebsd.org; phk@phk.freebsd.dk; rwatson@freebsd.org; davidxu@freebsd.org; grog@freebsd.org Subject: mysql performance test results under FreeBSD-7.0-CURRENT Hi all, I did make some mysql performance tests under FreeBSD-7.0-CURRENT with=20 various scheduler and compile time options. It seems like mysql(BUILD_OPTIMIZED=3Dyes, BUILD_STATIC=3Dyes,=20 WITH_PROC_SCOPE_PTH=3Dyes)-libpthread-tsc-sched_4bsd+preemption gives better performance. The test results are at: http://www.mnbsd.org/ftp/mysql_test_results.txt There are several things I didn't test and this leads to some questions: 1. I didn't make test with Poul-Henning's CPU accounting patch. Somehow=20 I can't apply it (http://phk.freebsd.dk/patch/cpu_acct_2.patch) cleanly. Where can I find latest patch? When this patch will be included in CURRENT? 2. I didn't make test with Robert Watson's patch=20 (http://www.watson.org/~robert/freebsd/clock/)? Does CURRENT src tree=20 include it? If not when this patch will be included in CURRENT? 3. I did make tests with default malloc in CURRENT. I'm confused what=20 malloc options should try (jemalloc? phkmalloc?) What is the default=20 malloc in CURRENT? How to use these different mallocs? thanks in advance, Ganbold _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org"
