Re: question about monitering pv by using jcae

How do you know that it's the monitor update that is lost, and not writing the new values from pyepics that gets out of sync?

For such a test, I think you will get better results by making your IOC generate the updates itself.

record(calc, "counter") {

  field(SCAN, ".1 second")

  field(CALC, "VAL+1")

}

Any such record will generate 10 updates per second, without having to write anything to the IOC.

Generate enough of them and see how far you get.
