They must be doing something right. THIS IS NOT MEANT TO BE FLAME-BAIT, but this is the reason why we worked on the VM system in FreeBSD. Whether or not it gets the approval of all on how we made the changes, we did and it works better than the original FreeBSD/386BSD VM. ANYONE developing a *BSD can look at what we did and do it better if they want. There is NOTHING at all intrinsically bad about how the (386,Free,Net)BSD VM works -- it just needed a little work. DG and I on the FreeBSD team noticed that the VM performance was sub-par, and started working on it right-after FreeBSD V1.0 (actually I started on it almost 1yr before that.) There are some problems with Linux VM too, and we could learn for those mistakes. Also, there is a significant and subtile bug in the scheduling algorithm in the scheduler on *BSD... It is a simple fix, and makes X appear to be much more snappy when other processes are running on the system. Again, there isn't alot that is totally broken in *BSD, but it just needs a few fixes. I think that it is time for a truce on these flame-wars, and attempt to learn from each of the BSD/(Free-U**X) variants. John dyson@implode.root.com
