Which operating system do you use for your servers?

I use Gentoo Linux, for a wide variety of reasons. Performance is a big one, with the least amount of RAM utilized on startup after a fresh install, startup times to all-services-responding of around four seconds, and broad support for operation in a cluster: distributed computing. By default it compiles packages from source, allowing the installed packages to be highly optimized for the physical hardware it is running on, however it also integrates binary package support and distributed compiling allowing one "master" host to orchestrate compilation across an entire cluster. This results in "from depclean" kernel compiliation times in the order of 40 seconds in my production cluster. I SSHFS mount the package directory from the master on the other hosts and simply install the binary packages it produces.

Hand-installing a new Gentoo build takes around ten minutes on a reasonably powered VM
