Moderate usage is 3 users curious about it and >beating on the compiler. Obviously, no X 8-). How fast does it run? I have run a fairly large kernel on a 386 system with 1664K. It runs OK until it starts swapping. (Actually it runs dismally because the disks are slow MFM 2:1 interleave and the system has to go to the disk for almost everything.) When it starts swapping, the disk light stays on all the time and it takes several minutes to run the shell script 'umount -af; sync'. The shell is bash (definitely too big). All known patches related to memory leaks and disk activity are installed. -- Bruce Evans (bde@runx.oz.au)
