Our *extensive* testing on this very topic has proven conclusively that FreeBSD stands up under loads with thousands of simultaneous connections, where linux falls down at around 800. The problem seems to be in the number of file descriptors allocated per connection. My personal best is 5,382 IRC users on one FreeBSD box, there are other IRC servers that have done over 8,000. Some of the linux diehards on our network are still trying to make a go of it, but even the latest kernels just don't hold up under heavy load. They may last a day or two, but eventually something in the networking layer seems to break down and the box becomes unreachable. Different apps with different load patterns may differ of course, but for something like ircd/ftpd/httpd FreeBSD will beat linux hands down on the same hardware, every time. In fairness, this isn't all that bad of a thing really. Linux was designed to be a desktop OS for having fun with unix, and BSD was designed as a server platform for serious work. Each of those is a good thing. Vive le difference I say. :) Doug -- *** Chief Operations Officer, DALnet IRC network *** Nominated for quote of the year is the statement made by Representative Dick Armey (Texas), who when asked if he were in the President's place, would he resign, responded: "If I were in the President's place I would not get a chance to resign. I would be lying in a pool of my own blood hearing Mrs. Armey standing over me saying, 'How do I reload this damn thing?'"
