[courier-users] Requsest for help: courier-imap authmysql slow?

I am testing the latest courier-imap.
I have a couple hosts with an older version and they are able to take 50 (5
processes requesting 10 logins) requests in 1 second.

The latest version of courier-imap handles about 1 login a second on
average.

Here are a couple related configuration options.
<SNIP /usr/lib/courier-imap/etc/imapd>
MAXDAEMONS=40
MAXPERIP=120
</SNIP>

<SNIP /usr/local/etc/authlib/authdaemonrc>
daemons=10
</SNIP>

These hosts are using the same mysql server. I have another test where I
can hit the mysql server several hundred times a second. So I don't think
the bottle neck is there.

Does anyone have an idea of what's going on?

Thanks
Haven



Here is part of my test run, you can see the host 'stats1-haw' is really
slow.
