I'm using the latest version of the gateway with EPICS base 3.14.9
together with the Channel Archiver as a client. I'm curious why the
Archiver records so much less data through the gateway than it does
archiving the IOC data directly. I'd expect some difference, but it
seems like the Archiver hardly sees any value-change events through
the GW.
I'm looking at about 1000 PVs with the MDELs set such that events
should be coming in at a high rate; in fact, the GW clientEventRate is
5000hz. But the archiver is missing almost all the value changes
(though it does seem to catch severity changes). I'm using the
'no_cache' option but it doesnt make any difference.
I'm purposely not using the 'archive' option. I dont remember the
older CA GW behaving this way.
