MeliaTech:
Jayell,
Thanks for your insight. We're going to try to limit the number of database calls by reducing the number of posts per page. Let's see if this will improve performance. Furthermore, we are simultaneously researching a couple other promising possibilities.
One thing that I think would probably help would be to fix the problem with the browser's BACK button, which is refreshing instead of going back to the browser's cached copy as it is supposed to do. Before this revision of the software, the BACK button went back instead of refreshing.
Further update (7-23): Changing the # of posts/threads per page was only moderately effective, and the system continues to have issues this morning. We will report back with any updates on our efforts from today.
I haven't noticed much of a difference with loading shorter pages, In a way longer pages are better, as then one doesn't need to load as often!
We were just told on another thread that NG does not want us to create links that open on a forum page - they should open in a new window. In this case, can you please take out the choices offered here:

and make all links open in a new window?
