Continuing the discussion from [Delay in tag update for tags that are using driven type scan class](https://forum.inductiveautomation.com/t/delay-in-tag-update-for-tags-that-are-using-driven-type-scan-class/49877/32): I have a customer on v7.9.18 that I think may be suffering from the global batching of writes problem.

Hmmm. Some more digging to do, then. ):
