Is FreeBSD better than CentOS for firing 40k concurrent connections (for Jmeter)?

Hi,

I am trying to run Jmeter to simulate 40k concurrent users and stress test a particular system. Putting aside the possibility that Jmeter may not be able to push such a high number (although I have read that it is at least possible to handle 10k concurrent threads on a very powerful machine), is FreeBSD a better OS as compare to CentOS to be used for my Jmeter machine?

Reason for asking this is that, I have found articles on FreeBSD for tuning and optimizing for maximum outbound connections, but seem to have little luck with CentOS. Personally however, I am more familiar with CentOS and would like to stick with it if possible.

Any input is greatly appreciated!
