QA Testing Tools

It looks like only two "universal" (supporting multiple protocols, including legacy) load testing tools remain, both belong to Microfocus: LoadRunner and SilkPerformer.

Microfocus LoadRunner and A href="" target="_blank">Performance Center (was HP, Mercury)

Microfocus (former Borland, Segue) SilkPerformer. SilkPerformer resources.

No traces of MicroFocus (former Compuware) QALoad can be found on the MicroFocus site anymore

IBM Rational Performance Tester

Oracle Application Testing Suite (formerly e-Test Suite from Empirix), several good white papers (Empirix still provides solutions for VoIP and Contact Centers - Hammer). Microsoft Visual Studio Load Testing Services
NeoLoad from Neotys
NeoLoad Free Edition, full-functional up to 50 users
Neotys blog

Akamai (former SOASTA) CloudTest

Eggplant Performance (former Facilita), "user-centric performance testing"

LoadStorm, "the easy and cost effective way to load test web and mobile applications"

SandStorm from Impetus

SmartBear LoadComplete

AutomAI (former NRG Global) AppLoader, "any application from the end user's perspective" (looks at bitmaps on the screen)

RadView WebLOAD

WAPT is a load and stress testing tool for web interface, inexpensive, free trial

eValid, "test complex web applications from inside the browser to work from the same perspective as your users"

Appvance IQ (former PerformanceCloud, PushToTest), allows to re-use Selenium, Sahi, soapUI test scripts and unit tests written in Java, Ruby, Python, and PHP for performance testing

There are many specialised load testing tools, many for Web or database testing. See, for example, by Rick Hower

Here is the list of open source load testing tools:

A couple of open source tools that looks more mature:

Apache JMeter (@ApacheJMeter)
JMeter Wiki, a collections of JMeter links
JMeter Links, a collections of links from stackoverflow
JMeter Plugins at Google Code
LoadRunner to JMeter – A successful transition by Swaraj Gupta
UBIK Load Pack, Productivity extensions for JMeter, and blog
BlazeMeter by CA, Cloud testing with JMeter and other tools, a great JMeter blog
OctoPerf, Cloud testing with JMeter and other tools, a good JMeter blog
RedLine13, Cloud testing with JMeter and other tools, a good JMeter blog
Flood by Tricentis, Cloud testing with JMeter and other tools

Gatling stress tool (@GatlingTool)

Locust, an open source load testing tool using Python (@locustio)

k6, "Like unit testing, for performance" (@k6_io)

Tsung, an open-source multi-protocol distributed load testing tool, developed in Erlang

Taurus, automation-friendly framework for Continuous Testing

OpenSTA Originally developed by Cyrano as a commercial tool. OpenSTA stands for Open Systems Testing Architecture. Other branches of the Cyrano code are commercial tools QTest from Quotium and AgileLoad.

JUnitPerf, a collection of JUnit test decorators used to measure the performance and scalability of functionality contained within existing JUnit tests

p-unit, an open source framework for unit test and performance benchmark

JUnitBench, JUnit extensions for benchmark and performance testing

Databene ContiPerf, a lightweight testing utility that enables the user to easily leverage JUnit 4 test cases as performance tests

Japex micro-benchmark framework

Hardware appliances can be useful if it is necessary to test network devices or simulate a big number of users with limited scripting requirements. For example, Spirent Avalanche or Ixia products.
Load DynamiX allows to test network storage devices (former SwiftTest).
Ixia's BreakingPoint, security and performance testing platform.
