hi! i have a Marwell (SMC) gigabit ethernet card (sk0) and have serious problems with performance.. the machine is a pc, amd 2000+ xp, 512mb ram.
tested with iperf (bidirectional test, udp transfer, not stream) and got 8-15% packet drop when the system was idle. then tuned the sysctl with these settings: kern.ipc.maxsockbuf=81920000 kern.ipc.nmbclusters=5000000000 kern.ipc.somaxconn=8192 net.inet.tcp.inflight.enable=1 net.inet.raw.recvspace=4096 net.inet.tcp.recvspace=131072 kern.ipc.shmmax=409600000 with these i got around 3-7% packet drop, but it's very high compared to zero :) my question is where/what should i optimize to not have packet drop at all, or at least reduce it as much as possible. thanks for your help!
