You are probably suffering from this aspect of Ignition's OPC client:

> Subscription synchronization is debounced @ 250ms and then delayed if necessary to ensure it happens no more frequent than 8 seconds. So sometimes it will be immediate-ish (250ms), and sometimes you'll get up to 8 seconds of delay.

Note that if there are _ **ANY** _ OPC tags have unknown OPC Item Paths, the corresponding OPC server connection will **stay** in that eight-second debounce as the tags retry.

For leased tags to have anywhere near sane behavior, there must be **NO** bad tags at all.
