Is your Mailman install on local disk or a networked filesystem?  I
have similar problems with an install over NFS and another over AFS,
presumably due to locking issues or something similar.

Running $prefix/bin/find_member is really fast the first time that it's
run, but future queries take around 30 seconds each.  Same with other
$prefix/bin commands.

This is on a dual Pentium III/800, 256MB RAM running Intel Linux (stock
RedHat 6.2/python install) on a 100MB switched network (the NFS server
is on the same subnet, but on the other install with AFS the server with
the mailman volume is on a different subnet).
