What could cause tags to load slowly in a certain tag provider but not another? They load slowly in a client session and in the tag browser in a designer.
Depends on the device, what driver you are using, and the communication protocol. It’s a very vague question and pretty difficult to answer without some more insight into how you are connected to the device.
It could be anything from the wrong driver to network latency.
They're memory, expression, and reference tags. They all take about 2 minutes to load in. The tags in the MQTT Engine tag provider load in a few seconds.
