How do I compare the performance of Node.js to that of PHP on Apache

t开发者_高级运维his might have been asked many times but, I want the specific performance testing methodology. I am having second thoughts on porting my application from PHP to Node.js since it involves some realtime data. If the performance tests that I make are satisfactory, then I think I will introduce some new modules which include realtime data.

Please can anyone help me with the task of how to test the performance. Thanks.

I think this question has been asked already. But since you ask "how" it's done, you might want to use Apache Utilities which can be used to benchmark the performance. This article walks through how one person used 'ab' to generate traffic, and dstat to monitor cpu and memory.
