This question comes up on -questions at irregular intervals, and answers can be found in the archives there. > First, what is the largest file size on a system? Is the limit part of > the filesystem structure, or just the kernel code? 8TB. Some commands - especially from ports - may have problems before you get that far. > Second, what is the maximum file system size? Again, where does the > limit lie, in the filesystem structure, or in the kernel? Depends on what the block/frag sizes on the file system are. I believe the smallest allowable block size gets you a 1/2 TB file system. > Finally, how many processors does the SMP code support in FreeBSD? Does > it run well with this many processors, or less than that? 16. I know it runs well with two CPUs, and have seen reports that it runs well with more than that. http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
