I want to upvote this multiple times. And we've reached a point where not only web devs should do this. Even the (Linux) open source world starts to move towards bad performance when a decade ago they broadly prided themselves by being not as bloated and slow as all the "Windows crap". Use your own stuff on a middle class machine with a spinning disk from 10 years ago once a week for the whole day to get a baseline. And sure there are exceptions, some programs just need a beefy machine, but many times there are mundane things like fi. a dozen unnecessary redraws of a list that go unnoticed on the latest threadripper with RAID-0 NVMe disks, but make the UI jump and twitch in an irritating way on slower hardware.
