JMeter - Load and Performance tester

•    Java

---

JMeter is a pure Java desktop application designed to load test functional behavior and measure performance. It may be used to test performance both on static and dynamic resources (files, Servlets, Perl scripts, Java Objects, Data Bases and Queries, FTP Servers and more). It can be used to simulate a heavy load on a server, network or object to test its strength or to analyze overall performance under different load types.

OpenSTA - Open Systems Testing Architecture

•    C++

---

OpenSTA is a distributed software testing architecture designed around CORBA. The current toolset has the capability of performing scripted HTTP and HTTPS heavy load tests with performance measurements from Win32 platforms. Results and statistics are collected during test runs by a variety of automatic and user controlled mechanisms. These can include scripted timers, SNMP data, Windows Performance Monitor stats and HTTP results & timings.

locust - Scalable user load testing tool written in Python

•    Python

---

Locust is an easy-to-use, distributed, user load testing tool. It is intended for load-testing web sites (or other systems) and figuring out how many concurrent users a system can handle. The idea is that during a test, a swarm of locusts will attack your website. The behavior of each locust (or test user if you will) is defined by you and the swarming process is monitored from a web UI in real-time. This will help you battle test and identify bottlenecks in your code before letting real users in.

Siege - Http load tester and benchmarking utility

•    C

---

Siege is an open source regression test and benchmark utility. It can stress test a single URL with a user defined number of simulated users, or it can read many URLs into memory and stress them simultaneously. The program reports the total number of hits recorded, bytes transferred, response time, concurrency, and return status. Siege supports HTTP/1.0 and 1.1 protocols, the GET and POST directives, cookies, transaction logging, and basic authentication. Its features are configurable on a per user basis.

Apache JMeter - Pure Java application for load and functional testing

•    Java

---

Apache JMeter may be used to test performance both on static and dynamic resources (files, Servlets, Perl scripts, Java Objects, Data Bases and Queries, FTP Servers and more). It can be used to simulate a heavy load on a server, network or object to test its strength or to analyze overall performance under different load types. You can use it to make a graphical analysis of performance or to test your server/script/object behavior under heavy concurrent load.

Performance - Client side performance tool

•    Javascript

---

In short about: This is an npm package to display statistics about your web pages, information such as CSS resources count, Google PageSpeed Insights score, information on how to fix performance issues, HTML errors and more in one custom web page. Tech details: This package mainly uses three plugins w3cjs (HTML test errors, warnings etc), Google PageSpeed Insights (a lot information, for example: how to fix main load/performance issues, load times...) and dev-perf (number of 404 errors, number of images without dimensions etc), The information collected is then displayed in an AngularJS based webpage.

tcpcopy - An online request replication tool, also a tcp stream replay tool, fit for real testing, performance testing, stability testing, stress testing, load testing, smoke testing, etc

•    C

---

TCPCopy is a TCP stream replay tool to support real testing of Internet server applications. Although the real live flow is important for the test of Internet server applications, it is hard to simulate it as online environments are too complex. To support more realistic testing of Internet server applications, we develop a live flow reproduction tool - TCPCopy, which could generate the test workload that is similar to the production workload. Currently, TCPCopy has been widely used by companies in China.

Fortio - Load testing library, command line tool, advanced echo server and web UI in Go

•    Go

---

Fortio (Φορτίο) started as, and is, Istio's load testing tool and now graduated to be its own project. Fortio runs at a specified query per second (qps) and records an histogram of execution time and calculates percentiles (e.g. p99 ie the response time such as 99% of the requests take less than that number (in seconds, SI unit)). It can run for a set duration, for a fixed number of calls, or until interrupted (at a constant target QPS, or max speed/load per connection/thread).
