Zitat von Silas Boyd-Wickizer s...@mit.edu:
Why do you believe that this should use 100% of ALL Cpus?
If you look at your synthetic test then you will likely find that
there are at any point in time only a few mail receiving processes
and mail delivering processes, and that these processes
Hello, I'm doing some experiments with a synthetic benchmark and
postfix. My current postfix configuration can deliver ~3000
msg/sec to 1000 virtual mailboxes; however, the system (16
core/4x4 AMD opteron) is ~90% idle. All logs and queues reside
in a RAM filesystem, so disk IO is not a

With 16 logical CPUs, in this configuration you'll find your CPU load
to be 1/16th of the theoretical maximum + overhead. Your report of 10%
is about right.
The system has 16 physical execution units: four quad core AMD
Opterons. In the configuration I described, 90% of total cycles
are
