Default FreeBSD Kernel Optimization

Hi guys,

Quick question. I've been using FreeBSD for many years, and whenever I compile a custom kernel, I've always made a point of going through and commenting out any devices I'm not using, such as ethernet cards, scsi cards, raid cards, etc. I was attempting to optimize the kernel and take a little load off the server, however I don't know much about the low level and how FreeBSD handles these unused devices during bootup. I was thinking about this earlier... does FreeBSD actually take a (tiny) performance hit from leaving those uncommented, or are they simply ignored on bootup and I'm wasting time going through and commenting them all out?

Not critical either way, I'm just curious.

Thanks!
