Multi-processes issues?

I found it difficult to ascertain or track Processor context switches. Various scenarios didn't make any difference to throughput, which was ultimately driven by the IMS transaction response time. I spent a good week fiddling with the code, examining chats and chaing suggestions. Real thread support would have made a difference I'm sure. I settled on a millisecond delay per unit of work to ensure all processes got a kick at the CPU.

As for the debugging, old Cobol programmers were in awe of the ability to dynamically debug and code the image while it was running. One point for our team.
