When profiling code with cprofile, I noticed that there appear a lot of numba entries referring to the numba compiler. I know that the computation time is high at the first run of the script due to compiling.

The attached screenshot however shows cprofile entries from a script which already should be compiled (The script was run at least twice and also the total computation time decreased).

Because the functions shown in the screenshot still consume a lot of time, I asked myself if I do anything wrong using numba. Additionally, it does not make sense to call a compiler function if the code is already compiled. Is there a way to find out if compiled functions are already in storage?
