Hi all, I did make some mysql performance tests under FreeBSD-7.0-CURRENT with various scheduler and compile time options. It seems like mysql(BUILD_OPTIMIZED=yes, BUILD_STATIC=yes, WITH_PROC_SCOPE_PTH=yes)-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 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 (http://www.watson.org/~robert/freebsd/clock/)? Does CURRENT src tree 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 malloc options should try (jemalloc? phkmalloc?) What is the default malloc in CURRENT? How to use these different mallocs? thanks in advance, Ganbold
