V26.5 OPC UA session/group tag limits
I was experiencing the same OPC UA collector UI performance issues described here. V26.5 is a HUGE improvement to my current workflows. Please pass on my thanks to the dev team.
To work around the now-resolved UI issues, I had been limiting OPC UA sessions to a single group with a maximum of 2,000 tags. With the performance improvements in v26.5, is there a recommended tag limit for sessions or groups?
I currently have several groups split across separate sessions (*_1, *_2, etc.). If the recommended limits have increased, it would be great to consolidate these back into a single session.

Will do !
There really shouldn't be a limit anymore in terms of a session or group. We suggest 25k tags in a DataSet, but that's to control the daily HDB file size. You could go more depending on how fast the data changes.
