How many sites do you have on your server?

14. All with mail service, dns , db engine.

I run 300 sites per server on my 1GHz 1GB server (not rackshack).I use cpanel as the backend my domain registration service (10MB free web hosting) and have had as many as 2050 sites on one server with 512MB of RAM and no down time ever.

125+ normal, commercial websites on one of our VMs running Centos 6.2. Really, the number of sites is only limited to the amount of traffic the network interface can handle. Today's Linux kernels and server hardware are so efficient and fast that typically the bottleneck becomes network availability; webserving is a very simple task and will not put the hardware or os under any strain, compared to other types of processing.

Have you experimented with other distros as the OS on your servers? Or did you just go with CentOS because everyone else uses it?

This depends on the number of sites. I offer hosting services, so I have linux servers which host only 1 site and also linux servers which host more than 250 sites!

None actually. I don't have a server...that I know of.
