Andrei,
That's percentage of what, exactly? For example, if one CPU is in a
low power state (I know Solaris 10 doesn't do this now, but I'm thinking
ahead to the future), then does the X% CPU cap represent the fraction
relative to a all-CPUs-full-on 100%, or to the reduced-power-condition's
100%?

Hi Gabriele,
One way to fix this would be have your amaivsd processes run in FX scheduling
class with priority 0 at all times. You just have to wrap something
like this around its startup script:
$ priocntl -e -c FX amaivsd
This should have a much stronger effect than renice(1).
We're also working on a feature called CPU caps for the FSS scheduling
class that will allow you to put an absolute cap on how much CPU (in percentage
points) can be used by any application.
You can use shares-based FSS scheduling today, to make Tomcat processes
receive more CPU cycles when competing with SpamAssasin or anything else
running on your system. See FSS(7) man page for more details.
Hope this helps,

Hello, don't know if this is the correct forum, but it is about performance.
I have servers with Solaris 10, postfix+amaivsd+cyrus, and tomcat running a web
application for imap mail and other things.
Sometimes customers' machines are stressed by spammers, and amavisd start to
steal a lot of CPU resources, lowering tomcat responses.
What is the best way to lower amavisd cpu requests so that SpamAssassina and
ClamAV processes will not steal Tomcat times?
