Search in forums is something that can quickly kill a server. I suggest you also rebuild your search database but first ..in VB you can disallow search indexing for certain forums. Make sure to do that for anything not important. Also PRUNE...PRUNE PRUNE PRUNE...too often sites with over 500k posts feel the need to leave post around from the beginning. This is COSTLY. What good are posts from 2 years ago? You can also consider using Google site search instead of VB search.

I believe VB also allows you to split up your search database to a seperate server...do it.

Search is easily one of the top resource killers for any forums.
