[Dark Navi]

As you can see in the image below, whenever I try to install a shoutbox, my Apache CPU usage spikes causing my forum to be unusable.

The first two spikes are from vBShout 6.x.x Pro, and the final is from Inferno Shout 3.0 (It was fine until like 7 members connected to the site)

This is strange as I've never had this issue on the exact same server specs with vBulletin before.



Details:

vBulletin 4.1.12
HDD 2x 500 GB SATA
RAM 6 GB DDR2-RAM
CPU AMD Athlon 64 X2 3400+, Dual-Core

Possible Conflicts:

vBH tabs?
Tabbed Forum Home? (Also takes like 2/3 seconds to load, quite irritating)

What I'm trying to ask is, is there a method of sorting this via like a different configuration? Maybe using a different httpd? or like editing something in php.ini?

I tried upping the max memory from 128MB to 256MB, and it seemed quicker, but admincp still displayed 128MB.

Any ideas guys?
