Please see my update above

I am relieved that things are working up to my projected speed based upon tests. One of the reasons that I moved to MCE from writing my own fork/threads implementation or using other CPAN modules/frameworks is because of the relative speed of IPC with MCE. So I was pretty worried about what I saw. My only wish now is that I can find out what changed and caused a problem before.

Marioroy Thank You for your contribution of MCE! While I agree with Discipulus, zentara, BrowserUK and other monks that developers should understand how to parallelize without the dependency of a framework, and I can and have, I appreciate when I don't have to think so much about this and develop tests to specifically validate that portion of code. As it happens, most of my parallelization needs have patterns that fit pretty cleanly into your framework. So there is minimal need for me to change my approach.

And with your addition of MCE::Flow, I'm actually looking at rewriting one of my existing workflows that currently takes over 4 hours to run. I have hesitated changing it previously because of concerns about how much coordination code I would need to write to pipeline all of the pieces together. I believe that Flow will do much of that for me.

Thanks again!
