Hi All,
Is there a way to run a speed test on a python node to understand how long each section of code is taking to run? I have a node with around 1200 lines of code and I’d like to understand where it can be improved to speed it up. I know there’s the Profiler widget, but that only tells me the total time, not the time for each line/section
Thanks,
Matt
I usually just import time and do something like this:
Though there are more advanced standard Python profiling modules as well.
Edit: Here’s a quick implementation (I usually import the Timer from this module):
201112_GHPythonTimer_00.gh (2.0 KB)
Edit 2: There’s also the .NET Stopwatch class (known from C#/VB):
from System.Diagnostics import Stopwatch
sw = Stopwatch()
sw.Start()
foo = 0
for i in range(100000):
foo+=1
sw.Stop()
print sw.Elapsed
Also check out the timeit module to get more accurate measurements for simple snippets.

Awesome, that’s just what I needed, thanks!
Out of interest, do you know why there’s a discrepancy between the timer duration and what the profiler shows?
The only code I have before the timer starts is a few imports and the definition of the timer itself:
Your example has a difference of around 33%(10ms) which isn’t so bad, but mine is out by almost double (30ms)
That’s likely due to the cost of inputting and outputting data (i.e. setting appropriate type hints on the inputs, and wrapping data in appropriate types on the outputs):
