Top Forums Shell Programming and Scripting BASH Execution Delay / Speedup Post 302933393 by gmark99 on Thursday 29th of January 2015 05:01:21 PM

In my case, "my_job" does some database queries and decides to call a function that will result in a cross-processor message and then wait for a result to be returned.

I would still benefit from a lot of jobs in parallel if they're just waiting for results from another machine, right? This waiting for outside resources is the basic reason for my wanting to run so many jobs in background.

Am I missing anything, or am I on the right track?
