So after doing the change from vB to Xenforo today this afternoon things went a bit strange. Both my CPU Usage and VM usage shot up to 100% on my shared hosting. Which brought my site to a standstill.. I was ready to turn everything back to vB but I decided to try to fix out what is going on. I have been running 2 vB forums on my shared hosting with URL jet for 5 years now, and never even got any where near to 50% So what went wrong? I had 6 members online, 10 guests and 6 robots and that was it. The hosting had this to say: Funny how this never happened using vB Anyone got any good ideas why this would happen?
