I just made the move from VBB 3.8 to Xenforo 1.4.7. I like the functionalities and design, but some how. With the same database, same user online. Xenforo seems to use 5 times more resources ( server load 5 time higher). My server load used to be round .6 to 1. Now with Xenforo ( with litespeed cache mod installed) is always around 2.5 to 5.
So, is there anything i can do to optimize Xenforo more?
