quick-mark: How Latency is Measured

our latency measurements target the hardware latency and are performed
using NetPIPE from:

http://www.scl.ameslab.gov/netpipe/ 


NetPIPE performs a ping-pong transfer of various-sized packets to measure latency as
well as throughput. The hardware latency is characterized by the transfer time of the
least amount of data. The number is calculated by NetPIPE by measuring the round-trip

time and then dividing by two.


netperf can also be used to test for latency, and allows for latency testing for both TCP
and UDP using tcprr and udprr. netperf can also be used to test with different sized
packets and can be run repeatedly for statistical analysis. For more information, go to:
