Open Source Benchmark Software

I/O performance Analysis Tool

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

Collectl is a light-weight performance monitoring tool capable of reporting interactively as well as logging to disk. It reports statistics on cpu, disk, infiniband, lustre, memory, network, nfs, process, quadrics, slabs and more in easy to read format.

This is an iperf3 for windows GUI startup program, no need to install. Just run it directly. Supports two startup services: iperf3 server and client.

NetIO-GUI is a Windows frontend for the multiplatform commandline utility 'netio'. It measures ICMP respond times and network transfer rates for different packet sizes and protocols. All results are stored in a SQLite database file and can easily be compared. NetIO-GUI is preferred to rate the quality of peer-to-peer connections like VPN. Download as portable 7-Zip or as setup file.

FurMark is an intensive benchmarking tool designed to evaluate the performance of graphics cards using fur rendering algorithms. This tool is particularly effective in generating high workloads that can significantly increase the temperature of the GPU, making it a useful utility for testing the stability and stress tolerance of graphics cards. By simulating demanding rendering tasks, FurMark serves as a comprehensive test for assessing the robustness and thermal performance of GPUs under extreme conditions. FurMark from Geeks3D is a free OpenGL benchmark tool for Windows that can also be used to check the stability of a graphics card thanks to a built-in stress test. FurMark rendering is designed to overheat the GPU making it a viral-like stability and stress test tool (also called GPU burner) for the graphics card.

Applet and .NET (C#) Framework for the Logitech G15 Keyboard to display Systeminformation on its LCD like CPU Usage, NetworkIO, DiskIO etc..

netstress is a client/server utility designed to stress & benchmark network activity of a given ethernet device or path using simulated (random) real world data and packet sizes instead of fixed data and packet sizes.

Master/node to gather and graph "everything" on your systems using Tobi Oetiker's rrdtool. It can optionally warn your surveillance software. This software package was originally called LRRD. The project. Please see http://munin-monitoring.org/

WebInject is a tool for automated testing of web applications and web services. It can be used to test system components with HTTP interfaces, as a test harness to create a suite of functional and regression tests, or for service-level monitoring.

The program thrulay is used to measure the capacity, delay, and other performance metrics of a network by sending a bulk TCP or UDP stream over it.

Both a network throughput testing tool and a simple demonstration of IPv6 socket programming. Also includes a reuseable IPv6 API emulation library.

This program lets you monitor and log latency between the computer where you run it and another host. That other host could be anywhere on the Internet. It's good for troubleshooting networks, or proving there is a problem. An option to log to a .csv file lets you easily import the data into a spreadsheet program for charting.

Packet Flood Generator as the name stands is a projet to produce a threaded traffic generator program, it has support for generating IP, TCP , UDP, ICMP and IGMP packets, also has as feature to keep the connection up.

This Screensaver-program use low CPU and RAM Choose a what must display information: CPU Usage RAM Usage Network Usage HDD Free space HDD Usage Page File Usage and Lot of personal settings !!!!

SysGauge is a powerful system monitoring and performance analysis tool for Windows that delivers deep insights into your computer’s operation. It provides real‑time visualization of key metrics across multiple domains: CPU and memory usage, disk I/O, network traffic, and active processes. The application features a customizable dashboard with live graphs, gauges, and tables, letting you track trends and spot bottlenecks at a glance. SysGauge supports historical data logging for post‑analysis and capacity planning, and offers alerting for critical conditions (e.g., high CPU load, low disk space). It includes advanced process monitoring with detailed resource breakdowns, service status checks, and network connection tracking.

LDAP Directory Server Monitoring tool with focus on 389 DS / Red Hat / Sun / Oracle ODSEE and Open LDAP. IBM Tivoli and Novell eDirectory. Other Directory Services are also supprted.

MuninLite is a single Bourne Shell script that implements the Munin protocoll as well as some Linux specific plugins. The motivation for developing MuninLite was to provide a simple Munin Node, using inetd on systems without a full featured Perl.

FBENCH is the throughput benchmark tool for measuring TCP and UDP performance between two systems. It also used as the networking stress tool. Originally it was developed as part of the FNET TCP/IP stack project.

pipeworks is a benchmarking tool for pipelines that is very similar to pipemeter. It writes its stdin to its stdout, while reporting the data flow rate to stderr. It features adjustable block size and bandwidth limiting capabilities.

MRTG-PME is a set of performance monitoring extensions to MRTG that allow historical graphing of OS performance data (CPU, memory, paging, disk, etc.) for Linux, Solaris and BSD. With no SNMP required, PME is arguably more secure than standard MRTG.

NetChat is a network version of the "chat" utility that comes with PPP. It is a general purpose network "conversations" tool, designed for network testing. It can also be used for (very) quick setup of a server for a new protocol.

"Traffic" is ethernet/ip traffic generator. The tool consists of server and GUI application. Typical configuration is to have at least 2 servers and 1 or more client machines, where the servers are controlled and results are displayed.

Web site load tester. Simulates multiple user types and counts. Includes proxy server for recording playback scripts, and log evaluator for generating result statistics.

EasyBSD is a modular automation script designed to assist in the extensive post installation process that is required in FreeBSD. The following are modules that are included with EasyBSD, Checks, Update, Security, Networking, Firewall, and more...
