Dear Andrew
Thank you for your help in advance
I keep checking the loading. it is running fine. the
load averages is not over to 1.0
System info:
Intel(R) Pentium(R) 4 CPU 3.00GHz
2G memory
for the sysctl var:
kern.polling.enable=1
kern.polling.user_frac=10
kern.ipc.somaxconn=2048
kern.polling.poll_in_trap=1
I don't run iperf and my switch is not managable.
could you provide any hints to check it?
and tune the system also.
Thank you again
last pid: 47008; load averages: 0.00, 0.02, 0.02
up
80+11:09:17 22:42:18
31 processes: 1 running, 30 sleeping
CPU states: % user, % nice, % system,
% interrupt, % idle
Mem: 100M Active, 1639M Inact, 201M Wired, 60M Cache,
