So you are saying that a given tofile() call returns only after 2 seconds !? Can you measure the getData() call time (just comment the tofile out for a while- I that doesn't use 100% CPU ..) ? (timeit module is needed - I think) Maybe multithreading might help - so that tofile() and GetData() can overlap. But 2 sec is really slow ....
