Hello, i follows up these thread and i think you all digging on the false possible error location......
I have made many performance tests with RELENG_4 related to RELENG_5 and DragonFly and Gentoo. My results was that RELENG_5 is half as RELENG_4 fast by disk-access (ata-related). I have seen that RELENG_5 with GENERIC Kernel and only modified option HZ=2000. the spread begind with Gentoo (mentoided from me as the slowest, but errare humanum est) Gentoo : 100% time consumption RELENG_4: 67% time consumtion DrangonFly Rel1.2 69-72% time consumption (i think preemtion) RELENG_5 134% time consumtion these tests are made on physically the same Hardware (real, not equal system, same system, same disk, same RAM) with the command: # cd /; /usr/bin/time dd if=/dev/zero bs=1024 count=1024k of=zerofile; rm zerofile the tests are made more then 3 times/period/system. I have made the tests to the beginning of stable-5, and by the release 5.4. after the Release from DragonFly. By the first time i have made a mailing on stable, and i become the answer thath these issues become fixed on RELENG_6..... so i think you have to wait on the developers.... :-(( best regards Michael _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
