I consistently get 9-12 second load times for the front page and 5-8 second load times for pretty much any other page on the site, which makes it hard for me to troubleshoot.

Most of the slowness we do see is due to vBulletin and server load.

We have seen a lot of new traffic:

There are currently 246 users online. 10 members and 236 guests
We also recently allowed guests to view full attachments in some of the forums, which chews up even more time.

Our sql server is still on a shared host, so that may be one of the performance issues...
