Hello, I'm trying to improve my 10GigE driver performance on FreeBSD 6.3. till now I found the following tcp parameters and set them: # sysctl net.inet.tcp.sack.enable=0 # sysctl kern.ipc.maxsockbuf=16777216 is there anything else I should think about regarding tcp parameters? 2nd question: I'm getting quite a high cpu utilization, about 75% for an iperf test. I'm looking for a tool such as oprofile that will help me find the problem. does anybody know something like that? Thanks, -Yony
