Speed can vary depending on a number of factors, I found the best results occur when using Memcache. You could turn on vBulletin debug information to check page generation times, this is my forums normal generation time (forum home):

This is simply a test forum, no mods but vB Optimise, my server also has XCache installed, when I turn vB Optimise on:

Not to mention the reduction in two queries and a chunk off another :)

you joined two days back and brought a really nice thing pretty fast. Will test it out.

Can you please explain, which 2 global queries does it reduce and which one it chunks off.

thanks

This looks interesting and promising if it does what it says.

Question doesnt vbulletin already cache templates?

Going to keep an eye on this one :)

vBulletin caches the template in a state ready to eval, but they are still called from the database on every page, but not with vBO :)

The query to fetch templates, and the query to fetch the style are both removed. The fetch user info query is the one with the chunk taken out, that chunk being the language/phrases since vB fetches that when fetching the userinfo.

this doesnt allow me to select styles :( the default style is the only always shown .. is that correct?

I'll check this out now, style switch should work, could possibly be a bug :)

Fixed, re-download and then re-upload the following file:
./includes/class_activecache.php

You'll be able to select styles correctly then :)

Just what i was looking for, thanks!!!! *Installed*

What extensions are you talking about?
