producerA.pyand check theput timeand compare it withproducerB.pyput time.
put time in producerA.py is higher than producerB.py, however the size of data being send through shared queue objects is more in producerB.py( 256x256 ) than in producerA.py (128x128).
I don't have much context if this is related to numpy or cpython multiprocessing, but this is definitely shouldn't be the case.
Ideally it should take more time in producerB.py beacuase the size of data is relatively higher relative to producerA.py.
This is my first bug report, I'm hoping to learn something...
Thanks everyone...
