You never saw my machine, a few months ago there were up to three real users and sometimes up to 6 logins. I like and use multitasking for working, but if one jobs eats a lot of CPU time, round robin is no longer good enough. The machine is a 386 20MHz AT with 2 MB RAM, three serial lines and a 70 MB winchester. It runs PC MINIX 1.5.10. A better scheduling algorithm would be very fine and not too hard to implement. I can understand that a multi-threaded file system means a lot of work, but a better scheduling algorithm should be ok. Michael Haardt (u31b3hs%cip-s01.informatik.rwth-aachen.de@unido.bitnet)

I'll have UUCP's, my wife doing word processing, and myself doing homework on my 386sx running 1.5.10 (using Bruce Evan's nice 386 32-bit mode software). We can feel it sometimes. A nicer scheduler would be nice. But...it's not like we're stuck to the scheduler out-of-the-box. It really boils down to how serious {ast, ph} are about keeping Minix as a nice, small teaching OS. If that's the case, I wouldn't want them to change it, but someone could write a "better" scheduler. If {ast, ph} wanted to become a serious alternative-to-Unix/Dos OS vendor, however,... -- Thomas V.
