Part of your high load problem is going to be due to the fact that vShare logs every connection that you get to mySQL. If you have a high traffic site, this can cause mySQL to have to right thousands, if not millions, of entries into the database. Unfortunately, there is no way to turn that off in the current version. However, you can periodically clear it out. By periodically clearing it out, your mySQL load will drop considerably.
