I've been doing a bit of messing around with my Vista Home Premium and i've come across the virtual memory section in advanced system properties. I've read a few articles on various sites and the advice is pretty inconsistent.

I initially set a custom size for the paging file size to the windows reccomendation of 3069mb for the initial size and the maximum size allowed, there didn't seem to be a massive increase in performance. I then had more of a fiddle and set the initial size to the same amount of RAM i have and the maximum allowed to around 3 times this. This seems to have increased performance slightl. Is anyone more clued up on this setting as i would like to utilise it to it's full potential. I have provided a screen shot of the virtual memory page and info of my system.
Thanks in advance
Stu

the answer is by sewrobb :
I've only got XP and the VM gives you a range, I think it's 10% of your RAM.

I changed it to "system managed size" and the VM shot up and noticably changed the performance.
