I have cut out the original correspondence to shorten this e-mail With respect to Poebus's reply what is the PIZZA challenge.? I presume it opens lots of small programs & does something with them. I was told that one of the advantages of the Unix system is it scales well. Phoebus'es comments would suggest that with this problem QDOS scales better. If Unix spends all its time swapping pages in memory then it really does grind to a halt. Would the problem be that the Unix box was running something like KDE? I would be surprised if you could not build a version of Linux on a modern PC Box running the equivalent of the software installation on the Q60 which could not operate orders of magnitude faster than a Q60.
