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.

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.

of incompressible flow analysis. This program solves Poisson equation
by Jacobi's iterative method which have many loops
- needs an MPI implementation (mpich and lam are supported by this port)
- needs an Basic Linear Algebra Subprograms implementation like atlas (default)
or blas (both are supported by this port)
tested on alpha (5), amd64 (5) and i386 (4 and 5)
Julian Elischer suggested a new category "net/benchmarks" because
he believes that too many ports are listed under net/. Checking
into it, I noticed that these two ports are described as
benchmarking programs. In the Porters' Handbook, the net
category is described as "miscellaneous networking software".
The benchmarks category seems more specific so I feel that it
is preferable.

SciMark 2.0 is a Java benchmark for scientific and numerical
computing. It measures several computational kernels and
reports a composite score in approximate Mflops (Millions
of floating point operations per second).

This is an ANSI C version of the SciMark2 benchmark,
translated from the original Java sources. The intent in
making this benchmark available in C is mainly for performance
comparisons.
