I've just read this article: http://dev.mysql.com/tech-resources/articles/move_from_microsoft_SQL_Server.html
There it says that MySQL on Windows is a good choice. (or is what I've understood)
In the article I don't understand if he says that MySQL on Windows is better than on Linux, or just that MySQL on Windows is good enough as Linux.
Now my doubt is: if I can choose a server dedicated to MySQL and I have to choose between Windows Server 2012 and a free GNU/Linux server distro, which one would have better performances?
May you guys help me understand this?
