The only difference I can find between the machine is that the

They both have the same data in the directory, the same
configuration, same software versions:
Also check syslog configuration. You need to keep syslog local4
to have any idea what's going on, but you must either send it
to a remote host or turn of sync (prefix with -, man 5 syslog.conf)
One disk sync per ldap log event can reduce performance more than an
order of magnitude.

I checked to see that both machines have the same logging setup and
the fast machine is being used by several clients while the slow one is
only being hit by my test queries. I'll keep that in mind though.
