I am a big fan of tcpdump (et al.).  With something taking nearly 30 
times as long to function, there is probably something relatively 
obvious if you know where to look.  I find that watching the traffic for 
a few minutes usually shines a light in the direction that needs to be 
investigated further.  There may be spurious DNS queries, or something's 
attempting IPv6 for something, or the likes.

Take a look at the traffic for a brief period (30 seconds - 5 minutes) 
and see if what you see makes sense.  Hopefully you will see something 
that doesn't make sense.  Chase that for a few more minutes until you 
can explain it.  Maybe it will be part of the problem.
