# now let's see the Parallelism
# you can use simple :p also instead of :parallelism
# remember :parallelism is all about real OS thread case, so
# you CANT modify the objects in memory only copy on write modify
# This is ideal for big operations where you need do a big process
# and only get the return value so you can do big works without the fear of the
# Garbage collector slowness or the GIL lock
# when you need to update objects in the memory use :concurrency
