  Description     : Network benchmarking utility for testing latency and throughput

sockperf is a network benchmarking utility over socket API that was 
designed for testing performance (latency and throughput) of 
high-performance systems (it is also good for testing performance of 
regular networking systems as well). It covers most of the socket API 
calls and options.
Specifically, in addition to the standard throughput tests, sockperf, 
does the following:

Measure latency of each discrete packet at sub-nanosecond  
resolution (using TSC register that counts CPU ticks with very  low 
overhead).

* Does the above for both ping-pong mode and for latency under  load 
mode. This means that we measure latency of single packets  even under 
load of millions Packets Per Second (without waiting  for reply of 
packet before sending subsequent packet on time)

* Enable spike analysis by providing histogram, with various  
percentiles of the packets' latencies (for example: median, min,  max, 
99% percentile, and more), (this is in addition to average  and 
standard deviation). Also, sockperf provides full log with  all 
packet's tx/rx times that can be further analyzed with  external 
tools, such as MS-Excel or matplotlib - All this  without affecting 
the benchmark itself.

* Support MANY optional settings for good coverage of socket API  and 
network configurations, while still keeping very low  overhead in the 
fast path to allow cleanest results.
