But this is probably no routing table, and single source and dst ips or very limited number of ips and ports. the entire problem with Linux is the route cache, try and generate random source ips and random source/dst ports and it won't even do 100kpps without problems. I would like to log into the machine and see 1.4Mpps going through 3 nics :) Brian McGinty wrote: >> I have a pre-production card.
