After some tuning, I now have 5.3 running at an :acceptable performance level. You may want to start testing the newer :versions of 5 current. I have noticed improved performance on my test :servers and believe that 5.4 will demonstrate an improvement in :performance. I know that the guys on the performance list would like :to get some good feedback if you find any specific bottlenecks with it :as well. : :--Nick FYI, I recently testing bridging/network performance on 5.4-pre and its about the same as 5.3: 25 to 30% more CPU load for the same traffic levels than 4.x. SMP drops packets at about 60% load and seems to have a lower capacity than UP. I'm sure some things are faster, but networking is a large component for most people I think. Threaded network stacks just don't seem to perform well, certainly not on UP. Linux MP works much better, but with 2 CPUs it has the capacity of FreeBSD 4.x with 1. So its hard to justify. FWIW, its quite a bit better with UP than DragonFLY, but dragonfly is much better with 2 processors.
