Jeff, I'm a little concerned with some of your statements. Netware may
be the greatest thing since sliced bread, but it isn't a full operating
system, so comparing it to Linux is sort of meaningless. Consider your
recent context switch claims. Yes, I believe that you can do the moral
equiv of a longjmp() in the kernel in a few cycles, but that isn't a
context switch, at least, it isn't the same a context switch in the
operating system sense. It's different - last I checked, Netware was
essentially a kernel and nothing else. Is there a file system? Are there
processes with virtual memory? Are they preemptive? Does it support
all of P1003.1? Etc. If the answers to all of the above are "yes"
and you can support all that and get user to user context switches in a
clock cycle, well, jeez, you really do walk on water and I'll publicly
apologize for ever doubting your statements. On the other hand, if the
answers to that are not all "yes", then how about you do a little truth
in advertising with your postings? Without it, they are misleading to
the point of being purposefully deceptive.
