Network Traffic Generator

Network Traffic Generator is used to check what
massive amounts of traffic of certain types will do
to an intervening network. It does not try to
measure throughput or response times.

Java Application Monitor API

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.

bonnie is a classic file system and storage device benchmark. It tests for linear character-based and block-based reads and writes, and the rewrite pattern. It also does a seek test. While other benchmarks do more sophisticated tests, bonnie is a very reliable and portable program that is suitable for basic testing. Optionally, you can test the operations with direct I/O (O_DIRECT on Linux).

HPC Challenge

HPC Challenge is a collection of benchmarks for measuring various aspects of system performance, such as flop/s, sustainable memory bandwidth, memory read/write rates, network bandwidth, and latency for parallel machines. It is designed for supercomputers, but will run on any computer with MPI-1 (Message Passing Interface) implementation and BLAS (Basic Linear Algebra Subprograms).

PHP Profiler Class

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.

Tijmp is a small and fast memory profiler for Java 6 and later. It can be used to find out what objects exist on the Java heap. It can show why objects are not garbage collected.

lmbench is a suite of simple, portable ANSI/C
microbenchmarks for UNIX/POSIX. In general,
it measures two key features: latency and
bandwidth. It is intended to give system
developers insight into basic costs of key

Cpipe copies its standard input to its standard
output while measuring the time it takes to read
an input buffer and write an output buffer.
Statistics of average throughput and the total
amount of bytes copied are printed to the standard
error output.

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.

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.

Likwid is a set of easy to use command line tools for Linux. It supports programmers in developing high performance multi-threaded programs. "Likwid" stands for "Like I knew what I am doing". It contains the following tools: likwid-topology, which shows thread and cache topology; likwid-perfctr, which measures hardware performance counters on Intel and AMD processors; likwid-features, which shows and toggles hardware prefetch control bits on Intel Core 2 processors; likwid-pin, which pins a threaded application without touching its code (it supports pthreads, Intel OpenMP, and gcc OpenMP), likwid-powermeter which prints the Turbo mode steps and measures energy consumption on supported Intel processors, and likwid-bench, a low level benchmarking framework. It works with any standard Linux kernel. Likwid is lightweight and adds no overhead during measurements.

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.

This suite currently consists of three programs,
Postal, Rabid, and BHM. Postal (the mad postman)
is a program that will deliver mail as fast as
possible via the SMTP protocol to test mail server
performance. Rabid (the mad Biff) will eat mail
via the POP protocol as fast as possible and
measure POP server performance. BHM is the Black
Hole Mailer to discard SMTP mail. All messages
sent via Postal have MD5 checksums appended, and
Rabid will check the MD5 to ensure that the
messages are not being corrupted.

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.
