stress testing tools

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. 　　Grinder-Grinder is an open-source JVM load

It also provides a replaceable interface for customizing data display, test synchronization, and test creation and execution. Siege-siege (siege) is a stress testing and evaluation tool designed for web development. This evaluates the affordability of applications under pressure: you can perform concurre

Exchange 2010 stress testing can use two tools, both from Microsoft, Exchange Server Jetstress 2010 and Exchange Server Load Generator 2010. Both of them can be used for performance and scalability evaluation of Exchange 2010. It should be noted that the two software should be evaluated in the test environment rather than in the production environment. Recommende

Do site webmaster is not sure which day offended the xx people, apart directly to the DDoS on the up to do you, black you, brother on D die you, encountered such a rogue, there is no way, so often to do their own site to do stress testing, to see the load capacity of the server is a necessary thing.

Of course, only these two indicators can not complete the performance analysis, we also need CPU and men analysis to draw a conclusion Ii. webshells Webbench is a website stress testing tool in Linux. It can simulate up to 30 thousand concurrent connections to test the load capacity of the website. You can search by Google.

Because each connection ends in a short period of time, a lot of time_wait operations are caused, so that the available port number is used up, so the new connection cannot bind the port.To modify the configuration of the client machine,Add the following to sysctl. conf: Net. ipv4.tcp _ tw_reuse = 1 indicates enabling reuse.
