Hello,

I am currently exploring breaking down a master IOC into several ones
running on embedded systems (ARM cpu).
Is there a way to benchmark or test their performance.
That is:
 * responsiveness to UDP request for PVs
 * responsiveness to TCP request for PVs
 * ...

In short, I would like to know if this change would be perceived by the operator.
Is there a recommended tool to do this?
Is there a recommended way?

You are looking for catime, which is part of EPICS Base, and somewhat documented in the CA Reference Manual.
