Faster is all relative. What are you doing? Is it networking? Then BSD is probably faster than Linux. Is it something Linux is optimized for? Then probably Linux.
A general benchmark? Who knows, but does it really matter?
At the end of the day, you should benchmark your own workload, but also it's important to realize that in this day and age, it's almost never the OS that is the bottleneck. It's almost always a remote network call.
