At the moment we have = these limits on our buffering: kern.ipc.maxsockbuf: 262144 net.inet.tcp.recvbuf_max: 262144 net.inet.tcp.sendbuf_max: 262144 I believe it's time to up these values to something that's in line with = higher speed local networks, such as 10G. Perhaps it's time to move these to 2MB = instead of 256K. Thoughts?
