program. Of course, you can use standard testing methods (publish your program and expect the best results), but you still decide to test the performance of your program in advance. This is a good sign!
Test requirementsTo better test your ASP program, you must first determine how much pressure your program will face in the future. Simply put, the pressure or load can be divided into the following figures:
The following are ten free Web load/stress testing tools, you can know how much concurrency your server and your WEB application can withstand, and the performance of your website. I believe that the development team of the ticket booking website of the Beijing Organizing Committee does not know such a test tool.

Using LoadRunner for load testing in large loads requires configuring some environment to meet the full range of resources under heavy load:1. In order to avoid the occurrence of "No Buffer Space Available "Error, the following configuration is required:1) Modify the registration form:* Set "Hkey_local_machine\system\currentcontrolset\services\tcpip\parAmeters\tc

After the test staff to do a week of stress testing, the pressure test report is formally released, it is also an end, but the n
Server performance stress testing tools include http_load, webbench, AB, and siege.
A webbench can simulate up to 30 thousand concurrent connections to test the load capacity of the website.

Web Server stress (load) Testing Tool
SiegeAn open-source stress testing tool that allows you to perform concurrent access to multiple users on a WEB Site Based on configurations, recording the corresponding time of all request processes of each user, and repeated in a certain number of concurrent accesses.Official: http://www.joedog.org/1.

Post: Unknown SourceHow many concurrent user accesses can your Web servers and Applications Support? Is the software faulty when a large number of concurrent requests occur? These questions cannot be answered by common testing methods. This article introduces Microsoft's free tool WAS for this purpose and its usage. In addition, this article introduces a Web application performance optimization method, and uses WAS to test its performance improvement

◆ Server Load Testing
It is also common that the server load is too large and the program efficiency is affected. We need to test this. Here I take the most common Apache server as an example.
The Apache Server comes with a tool named AB (apacheworkflow) in the bin directory. With this lightweight tool, we can test the server
Loadrunner11 is not used much. loadrunner9.5 was used most of the time before, mainly because of concerns about the stability of the new version. However, loadrunner11 has to be used in Windows 7, but it is unstable, you need to use it before learning about it ~
