in thread Writing to many (>1000) files at once

It is financial data... each file is unique and even lines that have the same key may pull different items from the record, though the output is all based on the same thing.

Files can be anything from a few bytes to a couple megs, really... all depends on how many securities they ask for.

    It doesn't sound like trying to "write" more than a file at a time gains anything from an I/O efficiency point of view then. You may get a gain in code organisation, but there are probably other ways to achieve that. Can you sketch the code structure and the structure of files on disk? (Not file contents, just how directories hang together and such.)

    How do the files get out to your customers? Is that the potential bottleneck?
