Web server performance/test tool

I'm looking for a tool that simply tests a web server which I developed an application on it.

Tool must tell me that entire web server or a page in my application

- can serve at most how many users

- can use how much CPU

- can measure tra开发者_如何学编程nsaction per second (TPS)

Please do not confuse my question for a kind of http(s) listening tools like Fiddler.I do not want to listen,I do want to test it (This is like "Can you run it" tool for a game)

ApacheBench (don't be fooled by the name) will load up your app and give you a count of how many requests per second you can deliver. In addition, it's concurrency options will give you an idea of usercount.

See also the Microsoft Web Capacity Analysis Tool.

You need two things:

1. A load tester. See these questions/answsers:

   • load test / stress test web services
   • Best way to stress test a website
   • Open source Tool for Stress, Load and Performance testing

2. On your server, use performance monitor to measure the things you're interested in (memory use, processor use, paging...) while it's under load. Performance monitor also has ASP.NET-specific counters.

Like Ian said, ApacheBench is a good starting tool. If you find you need something a bit more programmable or robust, the next free step up is definitely JMeter, which also happens to be an Apache Foundation project, and is a Java client application that can record a series of user actions on your site via built in proxy server and then replay them for X users / N minutes / Y iterations / etc... to simulate real traffic. You can even record different activity segments and play them back at alternate ratios (i.e. 20% submit content, 80% read content)

Myra,

I would think that most Apllication Server providers do have a monitoring tool that allows you to make that kind of decisions. For example, JBoss has JOPR or JON (same tool but the later is supported by Red Hat). Others like webappVM are specifically designed to run and gather metrics under a virtualized cloud. You need to look in what what have, budget, and what is available for that environment.

Hope this helps,
