Hello all,
We have a 2.4GHz Intel Xeon machine running FreeBSD 6.0-RELEASE-p2. Due
to heavy network traffic, CPU utilization on that machine is 100%:

Does anyone know whether a dual CPU system can help us improve the
situation? I was wondering if the software interrupt threads would be
divided between the two processors.
Any help/insight is greatly appreciated
Thanks!
