Forum VB4 is extremely slow compared to VB3?

[محروم.كوم]

I have a VB3 website here:
http://www.8wayrun.com/index.php

Code:
Page generated in 0.31988 seconds with 28 queries [Server Loads: 1.04 : 0.55 : 0.38]
It's very fast, and none of my users have been reporting any problems. However, I have recently begun testing VB4. This is running on the same server, at the same time and it seems to be running FAR slower.

Is this normal? Also, the CMS seems to have MASSIVE template caching issues...

Code:
Page generated in 4.82897 seconds with 103 queries (16 queries for uncached templates) [Server Loads: 0.96 : 0.54 : 0.38]
