I'm not surprised OSX is slower than Linux. Apple still has a way to go toward fully optimizing the Unix underpinnings for their hardware. They are also a few versions behind in the BSD they are using. I'm presuming you have similar settings for each setup.

As for the "processes" you see on Linux, in a nutshell Linux used threads and other Unix uses processes. That's one of the fundamental differences between Linux and other Unix flavors. Your actually seeing threads. Threads don't have the launch overhead that a process does so you should get better performance with threads.

I have noticed that on linux the mysqld runs as many processes and on
MacOS 10.2 it runs as a single process. Is this an architectural decision?
or have i configured the server incorrectly?

Thank you,

No, actually, it always runs as a single process.  What you're seeing
is that ps reports separate threads as processes on Linux.
