Subject: FreeBSD 5.3 Network performance tests

As promised, I've tested the basic network stack for 5.3 -RELEASE
The results follow:

Hardware:

Celeron 1.7Ghz processor
Dual onboard Intel NICs, fxp driver
Intel 845G chipset
256MB Ram, 120MB allocated to the kernel.

Setup:

Setup 1: Generic Kernel

FreeBSD 4.10: 40% interrupt usage
FreeBSD 5.3: 55% interrupt usage

Setup 2: 

The systems were stripped of all hooks, including firewalls,
gif and bpf inputs. 

FreeBSD 4.10: 35% interrupt usage
FreeBSD 5.3: 48% interrupt usage

Setup 3:

We typically use Freebsd with IPFIREWALL and 
IPDIVERT enabled. The setup had only 1 allow 
rule in the ruleset:

FreeBSD 4.10: 42% interrupt usage
FreeBSD 5.3: 58% interrupt usage



Thanks for your test results. Was DEVICE_POLLING enables in the kernel and
the sysctl?

Regards
S.
