Is it too slow or Am I doing something wrong?

[rstulug]

I used 30 SLC images and stackSentinel.py created 110 interfereogram when choose -c 4. The parameter --num_proc is chosen 56 (I have 56 core) to speed up the process but It has not finished for 3 days. Everthing looks correct, there is no error messages and the program creates necessery files one by one. Furthermore when calling run.py, I also specified -p 56. Below you can see the code that I used to create run files. If there is an error that I made, how can fix it or if it the same for everyone, Is there a way to decrease the computation time?

stackSentinel.py ./SLC/ -d ./DEM/demLat_N38_N39_Lon_E030_E032.dem.wgs84 -a ./AuxDir/ -o ./Orbits/ -b "38 39 30.25 32" -C geometry -c 4 --num_proc 56 -W interferogram
