My background being pretty much all Windows, I am a novice to this field. I have grasped some basics by reading some material on web and how-to books but event after extensive digging around on web for real performance numbers on various operating systems, I still haven't found anything useful. Most of the data I found were basically comparisons of operating systems running MySQL or PostgreSQL to see how many connections or simple look up queries they each can server per second sort of things. But nothing that would point to underlying operations like threading, cache-ing, time slicing, I/O, etc. Now, I must admit most of the material showed Linux having upper hand. But I am not convinced FreeBSD would be behind in almost all performance benchmarks from always hearing the legendary performance and stability characteristics of FreeBSD. Can you please shed some light on what I really should be looking for in FreeBSD to optimize it to it's best performance? Am I expecting something that is just purely not BSD's priority or philosophy, per se? Is there some material I can look over? (note: I've gone through the 7.0 Preview and Tuning documentation on FreeBSD's site already.) Thanks.
