Things seem improved after moving a few mega-threads from view. What I noticed was the site running fine, then a big slow down. After gaining access to the mysql database process log, every time the site went slow there would be a thread id in the queued processes. Each id corresponded to an extremely large thread. Threads like "your latest 35mm camera purchase" or the "deleted" thread. There were several Kodak ones as well. I'll get these threads back into view soon but locked down and we can create a "part2" for them. For now seems safest to stash them away. It's still hard to tell 100% if that was the issue.
Oh no! Say it ain't so! Not the DELETED thread!

I leave the digital work for the urologists and proctologists.
