all the better. i like speed to zip faster. that is why i am considering putting in a wireless n/ gbit network with verision 150 mbit backbone into my system and a hacked linksys router/firewall with freebsd kernel. that is why i have 3 computers, freebsd desktop, reactos desktop, and ubuntu 7.10 server, with reactos's kernel hacked to be much faster. steve ulrich wrote: > On 12/16/07, Mike Miller <mbmiller at taxa.epi.umn.edu> wrote: >> On Sun, 16 Dec 2007, steve ulrich wrote: >> >> > i think the real irony in this thread is that ubuntu makes the dogs >> > breakfast of linux more like freebsd in its operational elegance. >> > >> > fwiw - there are several things about freebsd's kernel which are >> > definitely nicer than what's available on linux. notably in the >> > networking realm. >> > >> > - 10GE optimizations w/TCP segment offload (linux might have this now) >> > - SCTP - admittedly of niche interest, but this just works on freebsd and doesn't DIY brain surgery >> > - soft updates for filesystem updates >> > - pluggable network stack w/netgraph >> > - kernel queues >> > - accept filters >> > - partial support for pf (which is just good enough to keep you from going to openbsd given how nice pf is.) >> >> I have to admit that I don't know what those things are.
