stow : Stow, a software installation management utility for Linux that offers a number of advantages over the tried-and-true Red Hat and Debian package management systems. With Stow, you can organize applications available in standard tar files and keep application binaries logically arranged for easy access.

iperf : Iperf was developed by NLANR/DAST as a modern alternative for measuring maximum TCP and UDP bandwidth performance. Iperf allows the tuning of various parameters and UDP characteristics. Iperf reports bandwidth, delay jitter, datagram loss.

rsnapshot : rsnapshot is a filesystem snapshot utility for making backups of local and remote systems.
Using rsync and hard links, it is possible to keep multiple, full backups instantly available. The disk space required is just a little more than the space of one full backup, plus incrementals.

I’d rather choose netperf over iperf. Iperf is known to have several drawbacks that can lead to meaningless and inconsistent results. See the following links :

You also have to be very careful in the way you perform your tests in order to be sure they’re statistically significant. There’re some very good advice about this at the end of the following email : http://lists.freebsd.org/pipermail/freebsd-performance/2005-October/001561.html

Benchmark is no small job.
