Ubuntu 12.04.1 Server
now rexx 411 amd64 - (upgrading from 410 to 411 fixed my system queue abend - see other post - yea!!)
So without command piping anything to an rxqueue stage, and no push/pull or queued() my rxapi overhead was about 7% (see other post) and stayed there daily. Some internal REXX usage I'm not clear on accounts for this I guess...
Anyway, I recently started using some rxqueue set and push/pull between processes and I'm now up to about 9% cpu overhead.
I get these percentages by taking the total rxapi cpu usage and dividing that by the total rexx process usage (currently same 4 all day long), as shown by Linux top TIME column at end of day.
I anticipate more usage of push/pull between processes, plus whatever rxapi is being used for internally by rexx, plus increased data volume and I'm getting a little worried...
My question is, are there any techniques that I can use, things I can avoid, etc., etc. to keep the rxapi cpu usage overhead to a minimum?
Thanks for the help!!
