Andrew,
Thanks for the tip. In my case, I've got pfil 2.1.10, and I too found
the PFILDEBUG flag in the Makefiles. However, I see zilch in my syslogs
from pfil, and I'm logging at "*.info" facility in /etc/syslog.conf.
Darren,
Any comments here? Is the PFILDEBUG thing in the Makefile a "bug"?

Subject: Re: ipfilter and backup software?
Jeff,
Did you look at the syslog? If you find a lot of ipfilter related log,
pfil could be the culprit.
I downloaded pfil 2.1.11 to use with ipf 4.1.13, and encountered
performance problem similar to yours. Later I found the Makefile came
with pfil set the DEBUG flag by default, which caused overwhelming log
messages under heavy traffic.
PFILDEBUG=-DPFILDEBUG
You can try to remove -DPFILDEBUG and recompile and reload pfil driver.

Hi,
Does anybody else run ipfilter on a system that does network
based backups, like Netbackup or Legato? Have you ever tested
your backup performance with and without ipfilter?
We run Netbackup 6.0 MP3 on two systems (with two robots), a
V490 (4 cpus) with an ADIC i2000, and a V210 (2 cpus) with an
ADIC i500. Both robots are hooked to their hosts via fibre.
Both hosts run Solaris 10 with ipf 4.1.13.
I've noticed that shutting off ipfilter on the host makes a big
difference (30% or more) in terms of robot thruput, as measured
by iostat and Netbackup statistics. As a result, I have to
keep ipfilter disabled on these two hosts.
Anybody else seen this?
