By benchmarking the system while the system isn't really doing anything really pessimizes the advantages of the FreeBSD choices. Linux is indeed much faster at doing nothing!!! I suspect that some intrepid individual could improve FreeBSD a little, but the risk/reward would be too severe. Think of it like this: since alot of desktops sit in idle loops much of the time, perhaps the Linux philosophy has been to improve such behavior :-). -- John | Never try to teach a pig to sing, dyson@iquest.net | it makes one look stupid jdyson@nc.com | and it irritates the pig.
