Isn't it amazing, an OS that has rewritten the networking stack to end up getting essentially the same performance as the BSD stack (of course only demonstrated under no-load) and was developed years later. Sounds like they have been running in place :-). Considering the effort that Linux has taken, re-working the existing free OS would have been much more efficient. I guess the good thing is now that we have two major Free OSes. It was so interesting to see the lmbench results posted by a previous poster and how when the code was "done right" in Linux, that it didn't perform significantly better/worse. In fact there was a very curious difference in running a real program (the shell results), as opposed the the hello world test. I won't interpret the results, but the numbers speak for themselves. This is part of what I have been talking about where small benchmarks don't always show real-world performance. Kind-of makes Linux look like an educational exercise doesn't it? If Microsoft could sell MSDOS so long, I guess Linux can make it also. :-). Since it is obvious that FreeBSD and Linux under light load appear to run with roughly the same performance (plus or minus some design tradeoffs), I suggest that Linus join the FreeBSD team to continue on the long lived BSD development effort. This will allow us to start with our already very good light AND heavy load performance and improve it further (there is alot more scalability work yet to do), and of course activate some of our more esoteric features. Wouldn't it be a much more efficient use of resources? John
