Hello Kevin,
I think the easiest way to compare the improvements is to compare how long it takes to load tasks. To make things more complicated, you can use the minute duration unit. Another part that affects performance is the work time calculation.

If the page doesn’t hang, it takes 16-20 seconds to load tasks on my computer.

On my computer, it takes 300-350 milliseconds to load tasks.
