What is the overhead of the trigger on VMS ?
Does it include process creation/image activation ?
Or could you have some process waiting for the trigger to happen ?

In what way is a trigger better then to have a process
waiting in the MQGET call ? That would, as I understand,
at least give you low latency, not ?

We are not using ACMS, if that matters...
