It is certainly an achievement in technology (IMO.) However, the performance of certain ops was quite slow. I passed around some performance numbers to -core, but have lost my harddrive with the results. Please don't take my performance comments as putting down the Mach or Lites projects -- otherwise they are very interesting -- but OS perf under certain circumstances was very far behind FreeBSD/Linux. There are many reasons for using the Mach based OSes, but perf is probably not going to be one of them. In particular I remember fork/exec as being maybe 10x-20x slower... Perhaps someone in -core could forward my results that I had measured? John
