Subject: conntrack performance test results in INVALID packets
Date: Fri, 18 Jul 2008 11:39:41 +0200 [thread overview]
Message-ID: <488064DD.5080509@bock.nu> (raw)
Hi,
I'm performance testing a firewall with netfilter connection tracking
based on Fedora Core 9 and I'm having some problems.
Every now and then the firewall drops packets in the state "INVALID".
The test setup is as follows:
- I'm using plain HTTP as test traffic, nothing else.
- Client is an ApacheBench (ab) client.
- Server is Apache.
- HTTP connection keepalive with a maximum lifetime of
30 seconds per TCP session.
With 100 parallel TCP connections, it works. With 1000 parallel TCP
connections, I start seeing INVALID packets.
Can somebody point me in a direction where to search for the root cause?
best regards
Bernhard
