I'd personally increase the var_size if you're using Guest caching (128mb), run the system test to make sure vB Optimise is operating correctly.

Additionally..

1) Make sure you've enabled Guest Caching
2) How many guests do you usually have roaming?
3) Is there any other cache settings you've left disabled?

hi Deceptor

Thanks for the reply.


I did var_size 128M.


1- yes enabled Guest Caching.

2- Cookies and HTTP Header Options >>" Session Timeout is: 1500" >> The number of visitors to this period of time from 1200-1800

3- vB Optimise: Cache Options on my forum:

Hi Projje,

First of all - while vBSEO may make a positive impact on your forum it is also very load bearing. I would firstly recommend you run your site for a few hours with vBSEO off (either during peak or low traffic times), to see if the load you're experiencing shifts at all.

In addition you can also trial this with any other modifications you have, disabling 1 at a time for a period of a time to see any impact on load - A trial/error method that should shine light on anything that's causing your situation
