For example, I have a netra T1 105 working as a bridge between two vlans in order to use ipfw+dummynet to create packet loss and latency tests in a platform that was already deployed (quick and dirty solution). At the moment I configured the machine to do the job and made some benchmarks but haven't yet optimized anything so I can benchmark it later on to see the optimizations effect. This is the first time Im working with a sparc64 box with freebsd and I would like to know what improvements can be done in terms of specific sparc64 optimizations (ex. gcc flags/cputype), kernel/tunables recommendations, comments onthis specific job (bridging and messing with the packets in layer 3) or any other usefull info. You can find the base configuration of the machine here: http://nullpt.googlepages.com/netra.txt Thanks in advance for your time! Regards, -- Alexandre Vieira - nullpt@gmail.com
