I don't really know threads but I wonder... could threads speed this up?

Threads don't magically enhance the power of a processor. If you only have one processor, and it's not sleeping while some device is slow to respond, then it can't suddenly get any more effective by spinning off multiple threads.

Threads are useful for performance only when various parts of the process must sleep to await further data, but other parts of the process can continue to produce those data.

Threads are useful for design because they let you segment out the problem into loosely-coupled components, and you don't have to design a time-slicing pump to accomplish it.
