It's bloating the kernel. It's a *great* thing to have in the generic kernel--I really like the visual editing--but it's just ballast in a custom-built kernel which should have tuned all this stuff already. If this sounds just like more bitching, consider what I was doing the last couple of days: a customer of mine in Munich wanted to get rid of all his Microsoft crap and move to FreeBSD running on dickless workstations. The good news is, I now have a good document on how to do it. I set up the stuff, set it up on his machines and told people to run around and boot the workstations. They all fell flat on their face: they only had 4 MB, and for some reason FreeBSD didn't recognize the last 384K. The result was that the systems ran out of swap before they could even boot to access the NFS swap. On the same machines, BSD/OS ran without a hitch. I've forgotten the exact values, but the boot messages looked something like: BSD/OS FreeBSD real mem = 4194304 3801088 avail mem = 2800000 1400000 Sure, it's a good idea to look at shadow RAM and things and turn them off if possible, but the kernel size is also a big issue too.
