I haven't found much discussion around this new event in the performance recording.

I've filtered the timeline in the attached screenshot to show only Compile Query and Query Execution events. As you can see, the queries are relatively quick (querying an optimized extract), but the dashboard spends a lot of time compiling queries in a parallelized manner across all of the worksheets. There appears to be some stretch of time where not much is happening at all.

The attached performance recording is of me just selecting a dimension in an action filter and applying the dimensional filter across most of the worksheets on the dashboard.

Unfortunately I can't share the workbook, but if anyone can point me on the right path I would appreciate it.
