Hi
Thanks for the reply.
kcachegrind uses cProfile, so not overly useful for what I want to do
Thanks
Matt

It usually works quite well for simple profiling.

Hi
I am trying to profile my NetCDF4-python code to see how to improve read
performance, which I have identified as the bottleneck. I have done this using
kcachegrind and line_profiler.
I want to delve a bit deeper into the library to see where the performance is
dropping. I can't work out how to use line_profiler with the @profile decorator
in the variable class. I also can't work out how to get kcachegrind to delve
into the library because the slicing syntax var[...] is not an explicit
function call, and I can't get var.__getitem__() to do the same thing.
Does anyone have any ideas how I could get more information from profiling the
netcdf4 library?
Many thanks
Matt
