Hello

for ipb forum, if 100 member online at a time . and if i choose vps hosting

how much ghz cpu and ram need?

Thanks

Assuming you are not getting control panels like cpanel/plesk, get 512MB ram. If it's lacking, upgrade to 1GB. Upgrades are easy for a vps.

CPU is mostly meaningless when it comes to VPSes.
