I want to run my linux server in a virtual machine on an already slow computer. Reason I'm not installing the server on MY machine is that the VM will be moved multiple times, so it's gotta be portable.
So, the linux distro's gotta be balls-fast. I'd "like" a desktop (obviously xfce here instead of kde/gnome), but i'm willing to learn terminal administration if the performance difference in xfce vs. no xfce is substantial. Heck, I'm even willing to compile my own kernel if that makes a big enough difference (although i don't know how that will play in on a portable VM running on different machines).
So 2 questions:
1) how much faster is a console-based linux than one with xfce?
2) in either case, which minimalist distro would you recommend as the fastest? i know it's a crap questions, and i've done my fair share of googling.... i've seen a lot of arch and gentoo, but i want your opinions
