Hello!
What would be the smartest way to implement fast cross-IOC loops that are high-priority?
Problem: The CA server tasks on the target IOC are low priority (for good reasons, I know!), so that - even with a fast synchronous device support -
any stupid slow-and-low record processing on that IOC will introduce delays, which leads to jitter or multiple CA updates before the target record gets processed.
Oh, yes: "fast" would be something below 200Hz.
Any hints welcome... Ralph
