Definition Queries in Pro are very slow to update

[MollyMoore]

I've been generally frustrated with Pro's lack of ability to complete simple tasks without being so slow that it is unusable. Most frustrating right now, is the speed that it takes for Pro to update after setting a definition query on a layer. Is there some reason why this is so slow or something I can do to make it faster? 

Currently, if I set a definition query, it will take around 30 seconds to a couple minutes for the window to become active again.

Two years later and the issue is still present in my case. Nevertheless, the time reduced to about 10 seconds delay before I can resume work in a layout.

I'm still expieriencing the same issue. As soon as the quiery is deactivated, it's faster again.
