Re: Comparison of FreeBSD/Linux TCP Throughput performance

2009-10-17 Thread George Neville-Neil
Hi, Trying to chime in with a few pointers here. Things to check when doing a TCP benchmark on FreeBSD. In particular make sure to adjust theses: net.inet.tcp.recvbuf_max: 262144 net.inet.tcp.recvbuf_inc: 16384 net.inet.tcp.recvbuf_auto: 1 net.inet.tcp.sendbuf_max: 262144 net.inet.tcp.send
