Dear List, I feel my freebsd box is reaching his limits. I'm doing load-balance with a pf (round-robin + NAT) in front of 3 web and 3 database servers. Everything works fine with 100-120MBit/s, but if it reaches over 150MBit/s to 200MBit/s or even 300MBit/s, the connections are stucked, nobody can connect to the server. I checked it via "nload". And every time it goes over 150MBit/s it stars to drop some connections. I have 40,000 connections at the same time. Could it be because the pf? I mean it reaches some maximum throughput? When i'm running the iperf from inside the NAT, it does only 300-400MBit/s, but if I'm running it from the firewall itself, it does 600-700 (it depends on the traffic). The servers are connected to each other via GBit. Thanks in advance, -- Adam PAPAI E-mail: wooh@wooh.hu
