> Now my ?'s are: > 1. How many users do you think I run comfortably offa this config. Lots. It depends on what your users are doing, so it's hard to say. Email and news you should be able to handle 30-50 on the box easy. If they all start compiling stuff, 5-10. :) > 2. Do I have too much/too little disk and RAM (I heard a rumor that huge > amounts of ram can bog a sys down.) The newer Triton chipsets don't cache the memory above 64MB, so you take a big performance hit. And, if you don't use the Triton chipset you also take a big performance hit. > 3. Are my choices for the machines vs what they run wise? I think it's way overkill, but it depends on how many customers you have off the bat. It's better to start a bit conservatively than to go hog-wild and not make it cause you can't make your payroll. > 4. Is it possible to rebuild FreeBSD offa the cdrom discs? If you build a symlink tree off the CD, yes. > (I wanna -O3 the whole sys) No, you don't unless you have a compiler other than gcc to use. The optimizer in gcc for the x86 line has lots of problems. Any optimization level over -O has a higher chance of bugs. I avoid using anything but the default optimization just for safety's sake, especially if my livlihood was based on my machines being 'stable' and 'bug-free'. > Is it already optimised? Pretty much, although it will be nice if the GNU folks come out with a version of their compiler with Pentium optimizations. > And how much can I make in "one > command" (as claims walnut creek cdrom co. "you can build the whole > source tree in one command": what is considered the source tree? The entire source tree, and I believe all of the ports can be made as well, although it's not setup to do that automatically since most folks don't have that kind of disk space lying around. # cd /usr/src # make world [ Wait a couple days ] The entire machine is completely re-built and installed from scratch modulo the setup files in /etc and the kernel. > apps too?) The 'make world' w/out the source tree re-builds all of the binaries in the base system. > 5. Any good books on ISPing you recomend? I think the market is so new, and the complexities so varied that a good book couldn't be written yet. Nate
