:-)
Good question but I try to explain what motivates me to do it.
First reason (I think the most important :-) ) is that I want to learn
something new - I am new to python (I am unix/storage sysadmin but with programming
background so python was a natural choice for more complicated
sysadmin tasks).
Another reason is that our server (and I am responsible for it) has
many, many but slow cores (as I had written before). It means that
parallelization of operations is obvious - the developer is not keen
to spent much time on it (she is busy) - and for me this is something new
(among some boring daily tasks ... ;-) ) and fresh :-)
Another intention is to get some more knowledge about parallelization:
how to divide some task into subtasks, what is the most optimal way to do it, etc
And the last reason is that I love performance tuning :-)
