em1897, I'm curious how you are testing. In my testing, the 5.4 pre IP stack performed very well. I was able to get 100% more throughput than Linux (2.6.10 FC3) under heavy load on the exact same hardware. I was actually surprised at the difference because I have been a Linux Zellot for years. I didn't see any packet loss in my tests, but I do have good quality networking gear and servers. I was happy enough after my testing that I'm going to move my 4.x servers to 5.4 when it's released. I haven't tested dragonfly yet, but get all the performance I need out of FreeBSD. --Nick On Fri, 18 Mar 2005 18:55:14 -0500, em1897@aol.com <em1897@aol.com> wrote: > > > :Boris, > : I would agree that my initial impression of 5.3 was that it was slow > :compared to 4.x.
