QA Testing Tools

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

HP LoadRunner (former Mercury LoadRunner)

Borland (former Segue) SilkPerformer. SilkPerformer resources.

Micro Focus (former Compuware) QALoad

IBM Rational Performance Tester

Oracle Application Testing Suite (formerly e-Test Suite from Empirix) probably is the best-known Web-only commercial tool, several good white papers (Empirix still provides solutions for VoIP, IMS, and Contact Centers - Hammer; Empirix white papers).

Microsoft Visual Studio Stress and Performance Test Solution
SOASTA CloudTest, there is CloudTest Lite, free downloadable edition

eggPlant Performance (former Facilita), "comprehensive technology support including full web, client-side .NET, client-side Java, and TCP/UDP"

LoadStorm lowest cost cloud load testing tool

NeoLoad from Neotys

SandStorm from Impetus

SmartBear LoadComplete

AppLoader from NRG Global, "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 PerformanceCloud (former 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,
SoftwareQATest.com by Rick Hower

Here is the list of open source load testing tools:
http://www.opensourcetesting.org/performance.php

A couple of open source tools that looks more mature:

Apache JMeter
JMeter Links, a collections of links from JMeter site
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, JMeter Cloud 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.

Gatling stress tool

Eclipse Test & Performance Tools Platform Project

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 4.x extensions for benchmark and performance testing

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 provides cyber security solutions.
