Default to much virtual memory

hi all quick question(s) for anyone out there.

I was thinking of increasing my virtual memory as part of some tweaking I'm doing. I've read that you want to have your VM at 1.5-2x your ram size. One site I looked at suggested that amount of VM per HD you have. I have 3 physical HDs broken down into 5 separate partitions and 2 gigs of ram. So my questions to anyone who can spare a moment...

1. Does 4 gigs of VM sound right then?
2. Would 4 gigs of VM on each HD be worth wild...ie a total of 12 gigs of VM?
3. What about 4 gigs of VM per partition...20 gigs total?
4. Realistically is there a cap of how much VM would really be of any use?

Thank you very much in advance for any suggestions.

TO be honest, virtual memory shouldn't be used unless you have a good lack of RAM. virtual memory uses hard drive space for RAM, and hard drives are obviously much slower than RAM, or else RAM wouldn't be NEEDED

If say you have 2 GB of RAM, I'd have 2 GB of pagefile(virtual memory). THe most pagefile I'd EVER consider putting on a computer would be 3.5 GB, and that's only on a system with under a gig of RAM. Anything over 2.5 GB if Virtual memory these days will only start to slow things down as it taxes on the hard drive's speed.
