It showing percentage of the thread time in RUNNING state. But from documentation on Thread.State: Thread state for a runnable thread. A thread in … Read more
Each column has a description of what it means if you set your mouse to hover over it in Firebug. I’ll assume you can read up on how each column works on your own then. However, you have definitely come across some odd behavior which needs to be explained. The own time is the amount … Read more
The problem is that you imported send_email inside your method definition. I suggest you to use runctx: cProfile.runctx(‘send_email()’, None, locals()) From the official documentation: cProfile.runctx(command, globals, locals, filename=None) This function is similar to run(), with added arguments to supply the globals and locals dictionaries for the command string.
Pympler is a Python memory profiler that is compatible with both Python 2.x and Python3.x.
To really drill into your code try out stackprof. Here’s a quick solution on how to use it: Install the gem: gem install stackprof.

Here is a sample bit of code to time an operation: Dim sw As New Stopwatch() sw.Start() //Insert Code To Time sw.Stop() Dim ms As Long = sw.ElapsedMilliseconds Console.WriteLine(“Total Seconds Elapsed: ” & ms / 1000) EDIT: And the neat thing is that it can resume as well. Stopwatch sw = new Stopwatch(); foreach(MyStuff stuff … Read more

Updated. You can get output of profiler using io.StringIO() and save it into file. Here is an example: import cProfile import pstats import io def my_func(): result = [] for i in range(10000): result.append(i) return result pr = cProfile.Profile() pr.enable() my_result = my_func() pr.disable() s = io.StringIO() ps = pstats.Stats(pr, stream=s).sort_stats(‘tottime’) ps.print_stats() with open(‘test.txt’, ‘w+’) … Read more
You can use line_profiler in jupyter notebook. Install it: pip install line_profiler Within your jupyter notebook, call: %load_ext line_profiler Define your function prof_function as in your example. Finally, profile as follows: %lprun -f prof_function prof_function() Which will provide the output: Timer unit: 1e-06 s Total time: 3e-06 s File: <ipython-input-22-41854af628da> Function: prof_function at line 1 … Read more
