(05-02-21) stress testing notes for Web Servers

Today, I tried a lot of stress testing software.

Webstress:
The operation is intuitive and simple. You can test multiple URLs at the same time and test web pages that require form data submission, such as ASP, Perl, and CGI. However, it is commercial software and the trial version can only simulate 10 users. The test intensity is greatly affected. I have not found the registration code/registration machine for a long time on the Internet.

Openload:
A stress testing tool based on WebService technology. Register on the website and get a full-featured trial version. What username/password should I enter on the Web page after the result is run. Inexplicable. The most funny thing is that after I received my registration application, I sent an email saying that my phone number was wrong. I hope I can leave a correct one. He will ask me some questions about software registration. Note: He is not from China! I really don't know if he actually called the phone number that I had prepared ..

Apache jmeter:
An open-source stress testing tool. All are implemented in Java. Because it is based on the Apache project, I still look forward to it. But it cannot be downloaded. I have tried both the tgz and zip packages and an error occurred while connecting to the server. Depressed !!

Qaload:
It seems like a good tool. It is said that the Chinese national software testing center uses this software. But cannot be downloaded from the Internet. It is estimated that the service is charged. You don't have to worry about it.
