Netperf Tests

To accelerate an application with the Onload user-level transport, simply invoke the application on the command line as normal, prepended with "onload".

ie. Instead of:

  netperf -t TCP_RR -H myserver

do this:

  onload netperf -t TCP_RR -H myserver

and tuned for best latency:

  onload -p latency netperf -t TCP_RR -H myserver
