Hi list,
Today I changed the main gateway from our network from PIII 733, 512 MB
Ram running FreeBSD 4-STABLE to a Xeon 3.0, 1Gb Ram running FreeBSD
6-STABLE. But the performance of the network is worst than before.
The new machine is a Dell PowerEdge 1800 have one quad DLink DFE-580TX,
one quad Adaptec ANA-62044 and one on board Intel em. I enabled the polling
on all interfaces, set the HZ to 1000 and set kern.polling.user_frac=30, but
this does not happened.
Looking the new machine the high interrupt rate call my attention, follow
some infos:
