I would like to ask you all what your preferred method is to detect if

1) just run the app. on different machines (with diff. characteristics)

3) use hardware monitors such as cache-miss rate, ...

Hi,
I'm inclined to use a bunch of tools (htop, dstat, vmstat, iostat, free,
ganglia) to get a picture of whats happening on the system while my app
is running and then start making some inferences from the behaviour I
observe.
Having the ability to test your application on hardware with different
characteristics after coming to some tentative conclusions about the
charactertistics of your application sounds like a good option but could
be pretty time consuming.
