Pathrate is a tool that can estimate the capacity of network paths. An
important feature of Pathrate is that it is robust to cross traffic effects,
meaning that it can measure the path capacity even when the path is
significantly loaded. This is crucial, since the hardest paths to measure are
the heavily loaded ones.

pathChirp is a new active probing tool for estimating the available bandwidth
on a communication network path. Based on the concept of "self-induced
congestion", pathChirp features an exponential flight pattern of probes we
call a chirp. Packet chirps offer several significant advantages over current
probing schemes based on packet pairs or packet trains. By rapidly increasing
the probing rate within each chirp, pathChirp obtains a rich set of
information from which to dynamically estimate the available bandwidth.

load of a real-world busy file server.
It stresses the filesystem with multiple threads performing random reads,
writes and rewrites in order to get a realistic idea of the scalability
and the concurrency a system can handle.

There is an old Linux ELF binary of select in the pgms directory
of the distribution tar file with no corresponding source file.
Most probably time-polling.c should be used to build a binary
of select under FreeBSD, but for now select is just removed.
by SHIMAOKA Shunsuke, with some modifications to the Makefile by me.
The bytebench port was repo-copied to unixbench, before, to preserve
its history.

dkftpbench is an FTP benchmark program inspired by SPECweb99. The
result of the benchmark is a number-of-simultaneous-users rating;
after running the benchmark properly, you have a good idea how many
simultaneous dialup clients a server can support. The target
bandwidth per client is set at 28.8 kilobits/second to model dialup
users; this is important for servers on the real Internet, which
often serve thousands of clients on only 10 MBits/sec of bandwidth.
