For what I know, there are at least two levels of cache between your application and the actual file: python interpreter caches its reads, and the operating system does that too. So if you are worried about reading efficiently the file, I think you can stop worry. Instead, if you are processing files which might not have line termination at all, then reading in blocks is the right thing to do.
