I couldn't get Apache 2.2 ab to work on 7.0 at all. The ab from 2.0
worked fine...

Hi,
We was using one machine with FreeBSD 6.4-RELEASE running
apache-worker-2.2.3 + mysql, this server can answer high request from
one client using ab:

Using other hardware whit FreeBSD 7.1-PRERELEASE running
apache-worker-2.2.9_5 + mysql, we have a poor result:
{client}$ ab -n 2000 -c 1000 http://system_using_7.1-PRERELEASE

Test aborted after 10 failures

Looking for a problem on new server log we found:
kernel: TCP: [client]:50197 to [server]:80 tcpflags 0x4<RST>;
syncache_chkrst: Spurious RST without matching syncache entry
(possibly syncookie only), segment ignored
kernel: TCP: [client]:53845 to [server]:80 tcpflags 0x4<RST>;
syncache_chkrst: Spurious RST without matching syncache entry
(possibly syncookie only), segment ignored
kernel: TCP: [client]:53845 to [server]:80 tcpflags 0x4<RST>;
syncache_chkrst: Spurious RST without matching syncache entry

This error is harmless and occurs when the client closes the socket
before the TCP session has terminated. The RST have crossed and hit
the syncache. The same happens on 6.4 but it never told you about it.
All sysctl and apache conf are same on both server, is there a tcp
problem with FreeBSD 7.x?
Are you using the HTTP accept filter on the server? This may cause
the listen accept queue to overflow.
Please post the output of "netstat -n -s -p tcp" to further diagnose
the problem.
