Can you please test to see if there's been a performance increase? On my end, I feel like the increase is smaller than expected.

Yes, I confirm. It's much faster than before even though it's not ideal and still somewhat slow. I think the current increase is around 3x times faster.

Retested again - now it's in the category of being usable again. We can further optimize this in the future after careful profiling. Meanwhile, good job! 👍

Also a first step towards solving #907
