I've got a small to medium sized board, a few hundred posts a day, 2-300k posts total. I'm wondering for a site that size, does it matter which Linux distro it runs one? It's been on CentOS for the last few years and that's been working fine. But, I'm moving to a cloud server from Rack Space and I can run quite a few different os's. Just wondering if there's a better choice than CentOS.
