web performance tools

1. LoadRunner: It supports many common protocols and the versions supported by individual protocols are relatively high; flexible load stress testing schemes can be set up, and the
visual graphical interface can monitor rich resources; reports can be exported to Word, Excel and HTML formats.

2. WebLoad: webload is a performance testing and analysis tool launched by RadView, which allows web application developers to automatically perform stress testing;
webload tests the performance of the web by simulating the operations of real users and generating stress loads. A javascript test script, called agenda agenda,
is used to simulate the behavior of customers and to measure the performance of the web application in real environment by executing the script.

3. E-Test Suite: Test software developed by Empirix, a web application test tool that can be seamlessly combined with the application software under test.
The tools include e-Tester, e-Load and e-Monitor. These three tools correspond to functional testing, stress testing and application monitoring respectively. Each part of the function is independent of each other, and the
testing process can be coordinated with each other.

4. QALoad:
  (1) There are many test interfaces;
  (2) The system performance can be predicted;
  (3) The bottleneck problem is found through repeated tests;
  (4) The global load test is managed from the control center;
  (5) The scalability of the application can be verified ;
  (6) Quickly create simulated load tests;
  (7) High performance and price.
  In addition, QALoad not only tests web applications, but also tests some background things, such as SQL Server. As long as it supports the protocol, it can be tested.

5. Benchmark Factory: First, it can test the performance of the server cluster; second, it can implement benchmark tests; finally, it can generate advanced scripts.

6. JMeter: It is an open source testing tool designed for running and server load testing, a 100% pure Java desktop runner.
Originally it was designed for Web/HTTP testing, but it has been extended to support various test modules.
It works with modules for HTTP and SQL (using JDBC). It can be used to test server operation in a static or active database, and
can be used to simulate the operation of a server or network system under heavy load. It also provides an alternative interface for customizing data display,
test synchronization, and test creation and execution.

7. WAS: It is a free Web load stress testing tool provided by Micro$oft, which is widely used.
WAS can simulate the activities of a large number of users through one or more clients. WAS supports authentication, encryption and cookies,
and can simulate various browser and Modem speeds, and its functionality and performance are comparable to tens of thousands of dollars in products.

8. ACT: or MSACT, it is a set of tools for program stress testing brought by Microsoft's Visual Studio and Visual Studio.net.
ACT can not only record the detailed data parameters of the program operation, and display the program operation status with charts, but also the installation and use are relatively simple, and the results are easy to read. It
is a set of ideal testing tools.

9. OpenSTA: Its full name is Open System Testing Architecture.
The characteristic of OpenST is that it can simulate many users to visit the website that needs to be tested. It is a software with powerful functions and complete functions of custom settings.
However, most of these settings need to be done through Script, so before actually using this software, you must learn its Script writing.
If you need to complete very complex functions, the requirements of Script are still relatively high. Of course, this is also its advantage. Some programmers don't care about writing Script.

10. PureLoad: a completely Java-based testing tool, its Script code completely using XML. So, writing Script is easy.
Its tests contain text and graphics and can be output as HTML files. Because it is Java-based software,
PureLoad can enhance software functionality through the Java Beans API.
