15 seconds suggests a network (usually DNS) setup problem.
If it was local resources that was the issue the system
would fell as slow as tar in shells etc.
The good thing is it's reproducible. I would
use tcpdump to see what the box was trying
to do for each web request (preferably with
as little traffic hitting the box as possible).
# tcpdump host myhostname
Then you will be able to see any erroneous DNS request or whatever.
It should be quite easy to spot given the delay.
