In a situation like that, the two things I check first are:
1) DNS lookup failing, especially a reverse lookup..do you have Tomcat trying to look up a hostname for access logging, perhaps?
2) database connection timing out
Also, I would look at garbage collection, but I doubt that's it.

Yes, these occur internally and externally. There does not appear to be any network traffic that is causing this (according to the network people...). We're also seeing this on two different environments on two distinct networks.
After some more digging, there is just NOTHING happening on the machine. Dual CPU, with both cpu's sitting at about 99% idle. 1 GB of RAM, and it's not even being all used. Tomcat is using about 327MB of RAM with maybe 40(?) threads running.
When I submit my request to get the login page (not to process the login, just to serve the login page), I couple of the java threads will spin up and take maybe 3% of the cpu, but it still takes over 30 seconds to get the page.
Still stuggling for ideas.
-- DaveAre these results occurring when tested on a local area network as well?
I have had an issue like that, but it turned out to be a networking issue..not tomcat.
