good for testing performance with multiple TCP streams.
Siege is an http regression testing and benchmarking utility. It
was designed to let web developers measure the performance of their
code under duress, to see how it will stand up to load on the
internet. Siege supports basic authentication, cookies, HTTP and
HTTPS protocols. It allows the user hit a web server with a
configurable number of concurrent simulated users. Those users place
the webserver "under siege."
SysBench is a modular, cross-platform and multi-threaded benchmark tool
for evaluating OS parameters that are important for a system running a
database under intensive load.
The idea of this benchmark suite is to quickly get an impression about
system performance without setting up complex database benchmarks or
even without installing a database at all.
Current features allow to test the following system parameters:
* file I/O performance
* scheduler performance
* memory allocation and transfer speed
* POSIX threads implementation performance
* database server performance (OLTP benchmark)
Primarily written for MySQL server benchmarking, SysBench will be
further extended to support multiple database backends, distributed
benchmarks and third-party plug-in modules.

Blogbench is a portable filesystem benchmark that tries to reproduce the
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.
