thrulay-ng

thrulay-ng is a network capacity tester based on thrulay 0.6. It consists of a client (thrulay) and a server (thrulayd) between which measurement takes place. Simply start thrulayd at the machine which should act as a server:

$ thrulayd

Then start thrulay on the client machine with a command like:

$ thrulay -m 3 -t 10 host

This performs a TCP throughput test with 3 parallel streams (set by the -m parameter). The test duration is 10 seconds (set by the -t parameter). By default, thrulay will print a progress report every second (in TCP tests) and prints final statistics after test duration is over.

Simply run thrulay without any parameter to get a list of options that are supported. Also have a look at the manual pages of thrulay and thrulayd.

Features

TCP test: multi-stream support, statistics (throughput, minimum/average/maximum RTT)
UDP test: send fine-grained Poisson test stream, statistics (quantiles, duplication, packet loss, reordering)
Portable: runs on Linux, BSD (FreeBSD, OpenBSD, NetBSD), Mac OS X and Solaris
Client authentication based on netmasks
Uses faster gettimeofday() implementations if available
IPv6 support
