Originally I tried to use forking but since the child retained the memory from the parent, it's writing multiple things that I don't need in a file. So I switched to threading. I have something similar to import threading class test(threading.Thr...

The Python 2.7 update note says: A new version of the io library, rewritten in C for performance. I've played with Python 2.7 a bit, but I don't see any performance gain: >>> from timeit import Timer >>> t = Timer('f = open("E:\\db.txt", "r"); f.read(); f.close()') >>> t.timeit(10000) And the result: Python 2.6.5 -- 12....
