PHP Profiler Class performs code profiling and aids
performance optimisation by locating the areas of
code that consume most processing time. The
reports it produces provide information on the
number of calls to a code section, as well as the
percentage and total of time spent on a section.
Timing of multiple nested code sections is possible.
It requires function calls to be manually inserted in
the code being profiled.

http_load runs multiple HTTP fetches in parallel, to test the throughput of a Web server. However, unlike most such test clients, it runs in a single process, to avoid bogging the client machine down. It can also be configured to do HTTPS fetches.
Bootchart is a tool for performance analysis and visualization of the GNU/Linux boot process. Resource utilization data and process information are collected during the boot process, and can later be displayed in a PNG, SVG, or EPS encoded chart. Analyzing the chart will help in finding opportunities for optimization.

The Java Application Monitor (JAMon) is a free,
simple, high performance, thread safe, Java API
that allows developers to easily monitor
production applications. JAMon can be used to
determine application performance bottlenecks,
user/application interactions, and application
scalability. JAMon gathers summary statistics such
as hits, execution times (total, average, minimum,
maximum, standard deviation), and simultaneous
application requests. JAMon statistics are
displayed in the sortable JAMon report.

dbench is a filesystem benchmark that generates
load patterns similar to those of the commercial
Netbench benchmark, but without requiring a lab of
Windows load generators to run. It is now
considered a de-facto standard for generating load
on the Linux VFS.
Cactus is a general, modular, parallel environment for solving systems of partial differential
equations. The code has been developed over many years by a large international collaboration of numerical relativity and computational science research groups and can be used to provide a portable platform for solving any system of partial differential equations.

cdck is a simple program for verifying CD/DVD
quality. Even if all files on the disc are
readable, some sectors having bad timing and could
become unreadable in the future. The tool reads a
disc sector by sector, recording all reading
timings, and then tells you its verdict. It can
optionally write a timing table into a text file
usable by gnuplot, from which graphs can be drawn.
RUBiS is an auction site modeled after eBay.com used to benchmark e-commerce Web site technologies. It is currently used to evaluate design patterns, application servers, and communication layers scalability. Several implementations using PHP, Servlets, Enterprise JavaBeans (EB BMP, EB CMP, MDB, SB, EJB 2.0 CMP, Session Façade, etc.) are already available and new versions for JDO and .Net are currently developed.

cbench is a compiler benchmark utility that was
implemented to measure the effect of using
different compilers, compile time flags, and
runtime libraries on a set of synthetic micro-
benchmarks of C/C++ code. The set of small
benchmarks is easily extended.
XML Benchmark is a C/C++/Java XML parsers benchmarking toolset. Supported parsers include LibXML2, Xerces, Oracle XDK, Expat, RXP, QT, and Sun Crimson. Benchmarking fields include parsing (native, SAX, DOM), DOM manipulation, schema validation, XSL transformation, and XML signature and encryption.

sdd is a replacement for a program called 'dd'. sdd is much faster than dd in cases where input block size (ibs) is not equal to the output block size (obs). Statistics are more easily understood than those from 'dd'. Timing available, -time option will print transfer speed Timing & Statistics available at any time with SIGQUIT (^\) Can seek on input and output Fast null input Fast null output. Support for the RMT (Remote Tape Server) protocol makes remote I/O fast and easy.

hatatap is an HTTP scripting tool with scripts in XML. The scripts are
transformed into Java/o:XML before they are either executed from the
commandline, integrated into Ant build files, or run interactively from
Services/SOAP, performance tests with concurrency, test reports, regular
expression matching, and stateful Web site navigation. It is written in
o:XML and uses HttpUnit.
