See attached, which will open a zipfile that contains one file and reads it a bunch of times using unbuffered and buffered idioms. This was tested on windows using python 3.2
You're in charge of coming up with a file to test it on. Sorry.
Enter filename: test.zip Timing unbuffered read, 5 bytes at a time. 10 loops took 6.671999931335449 Timing buffered read, 5 bytes at a time (4000 byte buffer). 10 loops took 0.7350001335144043
