What Linux distro for a Rails app that needs to scale?
rsayers: I have no stats in front of me, but I have always been made to understand that BSD's (namely FreeBSD) handle high traffic better than linux.I personally use Debian for everything.  I can't imagine the distro making a huge difference really.  I've used Debian as a desktop os for some time, so when I needed a server os, it was easy to get going quickly.Switching from Apache to Nginx made more of a difference in my case than anything else I could have done I believe.
