I am about to develop a piece of software and I want to ascertain the impact it has on my system. The main things I am look for are load times, memory and CPU usage and shutdown time, although I would like to get as much information as possible. I know I can use my distro's system monitor to get some of this stuff, but I need precise data as I am going to be doing some before and after tests during my project. Is there anything out there (preferably open source) that will suffice?


It's looking that you need software profilers eg: for memory I use valgrind massif with linuxtools on eclipse.

If you are not restricted by system/gpl try dtrace on solaris/sunos if not try systemtap(eclipse + linuxtools) or gprof if you have source code.
