Designer Property Binding Window takes 30 secs to Populate

I am running Ignition 7.9.2 on Windows 10 with the absolute latest version of Java (8u131).

I am consistently seeing the Property Binding Window take a long time to populate. I’m usually staring at this for 30 seconds:

It’s pretty consistent. I even see it when launching my designer locally via http://localhost:8088/

I don’t see anything helpful in the Designer console.

Is this a known bug?

What is showing in the ignition service’s wrapper log file? Memory limit causing a GC pause, perhaps?

Unfortunately there is no information in wrapper.log, Designer Console, or Designer Log Viewer.

Under Gateway settings, you can increase the amount of memory the designer has access. Maybe that could help.
