I will be looking for distinct values in the BountyAmount column of the dbo.Votes table, presented in bounty amount order ascending. This machine has four i7 CPUs (hyperthreaded to 8) with a base speed of 2.4GHz. This is very efficient, as confirmed by the elapsed time of 13ms (all of which is CPU time).

When even a bit of React can be a problem on devices slow and fast alike, using it is an intentional choice that effectively excludes people with low-end hardware. I believe this range of mobile hardware will be illustrative of performance across a broad spectrum of device capabilities, even if it’s slightly heavy on the Apple side.
