<<You'll likely have to instrument the site to find out where this time budget is spent. Test first db access if any or could it be that you are doing something that could timeout (attempting a name resolution or whatever)?
Do you have some monitoring capabilities there? Or use https://msdn.microsoft.com/en-us/library/system.diagnostics.stopwatch(v=vs.110).aspx to measure

These tools can help determine what in a page is causing a slowdown. BUT, the issue I'm having is clearly attributable to the SERVER - the server doesn't even START to serve up pages until after 15 seconds has elapsed.
What I need to find out is what is causing the server to wait that 15 seconds - it appears that something is timing out.
I appreciate all the suggestions, but the issue is NOT page performance - it's SERVER performance.
Maybe I wasn't specific enough with my question, so let me re-phrase:
Any suggestions to find out why the server is waiting 15 seconds to serve up pages?
thanks,
