100k HTTP Requests simultaneously

Question

我必须测试我的其余API，以便在500ms内同时进行100k个API调用。有什么想法可以模拟它吗？

Answer 1

I would suggest to use JMeter too, it enable your test to create multiple concurrent jmeter server. Just to be clear you can control multiple remote JMeter engines from a single JMeter client and replicate a test across many computers and thus simulate a larger load on the target server.

To be honest, your target is quite high (100k API calls simultaneously within 500ms), ie you'll need a lot of jmeter servers. When you create stress tests, there are not magical recipes, guides or manuals. Trial and error is a fundamental method of solving this kind of problems.

In my experience, I first try with few concurrent users and see how the server react. Then increase the number of concurrent users till to reach an intolerable performance decrease or, worst, a bottleneck .

You will obviously need a load testing tool which can be run in a distributed mode, ie 1 controller and X load generators executing the same test.

• Grinder - scripts are written in some Python dialect
• Apache JMeter - this guy doesn't require any specific knowledge, you can create tests using simple GUI
• Tsung - is written in Erlang , known for capability to produce high loads even on low-end hardware.

See Open Source Load Testing Tools: Which One Should You Use? article for more information on above tools.

JMeter

The Apache JMeter™ application is open source software, a 100% pure Java application designed to load test functional behavior and measure performance. It was originally designed for testing Web Applications but has since expanded to other test functions.
