MySQL performance on Mac vs Linux I know that MySQL is tested more on Linux (Oracle has it's own linux distribution and you canot have LAMP wit MySQL (meaning MySQL has always focused more on Linux)

My intuition says that MySQL has a better performance on Linux than on any other OS (including FreeBSD based MacOS). But I don't have facts to back it up.

Can you point me to any references  which can help me determine whether moving MySQL from MacOS to Linux would give a performance boost= What has been your own experience?

I guess the only other way is to measure difference KPIs on both Linux and MacOS and then try to compare them. But I am trying to put more justifications for purchase of Linux ready hardware and cannot compare the two at the moment.
As seen in the PDF, there's no clear winner when we compare MySql performance between different Kernel.

Since all databases are different, you will have to do benchmark to be sure. I think the hardware spec will affect the performance more than the OS.
