我的PHP应用程序服务了多少资源？

Question

I'm wondering if there are tools that can measure how much resources (CPU/RAM) my PHP app uses?

I want to test my app by simulating multiple requests to different urls and see how much resources consumes? Also simulate multiple connections i.e. simulate that a defined number of users are using my app.

is it possible? what do you recommend?

Regards and thanks

If you're using Linux, top is the way to go ( at least for me ).

I keep one tab running top so I can watch the ram/cpu/etc as I load various pages/apps.
