Does this plugin delay main interface loading speed ？

there are distinct lagging after enable this plugin, can you optimizing it ?

I also experience this problem, and limiting the calculation to only past week will increase loading speed.

This addon will severely lag if it has to count a lot of reviews, which sadly doesn't make it usable longterm.

The biggest culprit done was "total reviews" on my end. After disabling it, the calculation got a lot faster. But Anki already calculates total revies in the stats page, so I bet there is a faster way to do it.
