Jeremy Zawodny’s has a good post on choosing FreeBSD or Linux for your MySQL Server? It falls at a really good time for me as i’m looking at new hosting options, on of the hosts that i’m really looking at offers your choice of FreeBSD or Redhat 7.2. The FreeBSD is much cheaper, but i’m much more familiar with Linux. Almost everything here relies on mySQL so that is another consideration. Read the article , its good stuff.
