/prog/ - how to benchmark the speed of an app

Name: s 2011-07-22 3:27

what is the best way to benchmark the speed of apps, say time how fast an app runs to completion? Is there a universal way to time an app runs to completion for both interpreted and compiled languages?

I dont want to know which programming language is fastest, I want to be able to time the speed of an app compiled with different optiimizations in a compiler, or time the speed of an app compiled in different brands of compiler, stuff like that

man time

pseudo-code

timer = current_time()

// code

execution_time = current_time() - timer

pretty simple dude

timer = current_time()

super_pipelined_remote_call()

execution_time = current_time() - timer

remote_call_causing_a_pipeline_stall()

pseudo-code

TimerManager mng = new TimerManager();
Timer timer = TimerManager.getNewTimer();
timer.setTime(TimerManager.getCurrentTime(timer))
//code
timer.getTimeElapsed()

this is the ENTERPRISE way

Your post lacks industry-standard `code' tags.
