Delays that are multiples of a minute always make me look for DNS
problems, since often a failed DNS lookup will timeout in one minute.

It could be the client is failing to look up the host.  If the client
has multiple DNS servers defined, it could be that the first couple are
not responding and it takes two timeouts until it tries the third and it
finally works.  

The server could also be trying DNS lookups before responding.  If so,
try to change the configuration to not do DNS lookups on the server, as
even if DNS is properly configured, it will slow things down.

If you're familiar with network tracing, you might sniff UDP traffic on
port 53 to see if there are DNS lookups timing out.
