I used 7.0-BETA3 and it is much worse.
Ouch. A lot of systems see improvement. Thanks for trying it
out. I hope that one of the people that has been doing the actual
work can now comment (I am just an onlooker), and that you can be
patient in the meantime.
Unfortunately, Kris, who often looks at these kind of issues, is
traveling for all of December and thus off the net.
Is there any other FreeBSD developer who can take care of performance
problems on many-cores systems? Seems like upcoming 7-RELEASE and
6.3-RELEASE would be completely unusable for us on that kind of systems
i.e. mostly on all modern hardware.
Now we also have terribly performing PostgreSQL on 8-core server. We
noticed the slowdown after moving PostgreSQL from 2xXeon 3.0
Apache+PostgreSQL server to dedicated PostgreSQL server. I collected
some stats (see attach) before moving to Linux.
With best regards,
