Based on some benchmarking I did a couple of years ago (in Java, if anyone was curious) the performance consequencess of different I/O buffering schemes (i.e., character-at-a-time, line-at-a-time, big-buffer-at-a-time, or all-input-at-once) can easily dominate total run time, swamping any performance gains from compilation vs. interpretation for file-oriented (non-compute-bound) processes. We know what REBOl does about my-file-data: read but do you know what type of I/O scheme your collegue's VO program was using? -jn- ------------------------------------------------------------ Programming languages: compact, powerful, simple ...
