I think the main network interface tuning is to bump up the RX and TX ring buffers. You can see these values using "ethtool -g". If the buffers are too low you will see Traffic Server generating a log of EAGAIN errors on the write system call (usin strace). > > We collect apache traffic server statistics by using > http://server:8080/_stats call from log server.
