I upgraded my server this weekend from a celeron 1.7 to a Xeon 3450 with 4 gigs of ram. In this upgrade I moved from a plain old Centos distribution to vmware’s ESXi hypervisor. I’m loving this. I have a firewall appliance, a webserver centos box with cpanel, a debian box with osgrid running and a centos box for my general “access” box from work.
The great thing? No slow down on any of them. I’m trying to dig up a windows license and play with it. I’m loving this.
