in reply to Re^7: Sharing Hash Question
in thread Sharing Hash Question

When I get back to work on Monday, I plan on updating the actual script. I'm dealing with files that have 30-45 million rows. I'm hoping spawning 10+ threads (on a 15 plus CPU machine) that are solely parsing the files should help reduce runtime; rather than sequentially working on each file one-by-one.

Here's my prediction: Even modified, your multi-threaded code ran significantly (an order or magnitude), more slowly than your single-threaded code.

And my solution: Iff you supplied me with the information I requested, I could process those same files to a hash in 1/10th the time that your single-threaded code does.

In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
