There were significant network and memory improvements in the 2.4 release. There were also some improvements that will have to wait for the next release, but overall it is much improved. FreeBSD 4.3 is much improved over 2.x and 3.x, so I'm not sure why that would be considered unusual or surprising. The memory system in Linux is still set up by default to give more speed at the expense of smooth load handling. It seems better, but you have to go into /proc and tune things to get better load handling. > the problem isnt the networking preformance, its the inability of the > memory system and the ethernet drivers to handle overloads properly. > They are modeled in a way that fails in practice. The way I understood it was certain drivers were more affected by this than others. Some were just fine, and handled very high loads. Another problem was multiple ethernet cards, but I forgot what caused that. A lot of that was addressed in the 2.4 release, and it seems to have made a lot of people happier. I can't test the difference because I have nothing but 10mbit ethernet. However, the 2.4 kernel is definitely faster in my day-to-day work, and has allowed me to delay a complete move to FreeBSD 4.x on my workstation. It was that much of a step forward. Now I can wait until I get proper 3D support for my nVidia graphics card. -- "We have nothing to prove" -- Alan Dawkins To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
