I am practicing algorithm and data structures. Therefore, I keep profiling my programs. Here is an example output from gprof: Each sample counts as 0.01 seconds. % cumulative self ...
I would like to be able to see what code in thousands of lines of source code is run most often and takes the longest. The purpose of this would be for optimization. Being able to see what parts of ...
I see the mantra of "profiling before optimization" repeated again and again here, on SO, and elsewhere. Although I certainly use profiling tools, I'm only occasionally surprised by the results. It ...
There are two areas to possibly optimize for speed in: Where the most time is spent The code that is called the most Which is the best place to start optimizing? Often code that is called the ...
I'm building an application with lots of components, a lot of which are third-party so I only know what I can get from their documentation. From time to time, by pure luck, I find out one of these ...
I'm writing a program similar to Python's timeit module. The idea is to time a function by executing it anywhere from 10 to 100,000 times depending on how long it takes and then report results. I've ...
