Ran TOP - the system is still at 99.5% idle while the page is loading.
I also ran ngrep (new tool to me - very  ) and the requests came
through very quickly - rules this one out too. The only one that I
don't really have a way to test is the DNS issue. The server is sitting
in our DMZ and our firewall rules say that our corporate network can
have total freedom to the lower security items (like the DMZ). As for
the DNS - the server is a single server with two virtual domains (name
based, not IP) and we have a DNS server pointing to it. Are there any
ways to test the DNS server configuration? Any tools that I can try? I
feel like this is probably going to be my smoking gun here.

On the server, you can use Dig - it's a pretty good DNS tool. On windows you
can use nslookup I think.
