| PackageDescription | 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 measuring 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. |
