In performance or trying to understand it? On my 1st 8088 (an Onyx machine) and 286 I was so impressed that I could carry 4/5/... 8 users on dumb terminals and still have very good performance on an interactive application (accounting data entry, purchasing,...). They were performing almost as well as the DEC PDP 11/70 minis. > Coming from a DOS world, I guess I was overwhelmed by all > the things that could be tuned in the kernel.

I was in a fog a long time as I tried to learn (what seemed) thousands of different components that resulted from the "do one thing and do it well philosophy". I now see that philosophy is severely under- appreciated. > There seems to have been > some built in tradeoffs over the course of the years in the unix-like > OS's, but it's still seems to work the same.

Consider the number of "brains and bodies" that have attacked the Linux kernel, GNU utilities, etc. If even a small portion of those resources had been diligently applied to the continued development, enhancement and maintenance of "traditional" OSs, I'm sure they would hold up well. But because big (and small) business is the biggest beneficiary of the "open source" and "free software" movement, they had no reason to continue with their efforts. They can sit back and take from the open source community and reduce their costs. And, as could be predicted, only a small percentage give back to the community. -- Bill
