I run my own bsd servers in virtual machines. We get over 12,000 page views per day, without performance issues and I only have 640K up speed. If you guys migrate over to a *bsd server, shout at me if you need help. My site is at
www.dominicanstotheusa.com if you want to check out performance. We run Simplemachines forum and tinyportal on FreeBSD 6.2.
If I had more IP addresses I would donate a VM for you to run on, but I have to buy a block of 8.
