I've noticed that some ipmon's have a VERY tight 
loop (where it does its ioctl call to get log data) ...
putting a sleep(1) in there helps out a LOT.

Also,  some versions of ipmon have a "-t" option
that kicks in code that does this (at the end of that
loop in ipmon.c)

Is ipmon supposed to be this heavy?   (3.2beta2)

With sar -u  (sampled every 5 minutes) and ipmon writing to a file or 
syslog  I consistently get...

%user	%sys	%idle
32	16	50

Without ipmon running l I get...

%user	%sys	%idle
2	0	98

Load Average is 1.05 and .05  respectively.

The box is no rocket but it should be using it's little pinky finger 
for what I'm doing - an older Sparc 1000 with dual 50MHZ SuperSparc 
CPU's.

The system is doing nothing else - should I even care?  Does this mean 
anything?
