I once spent around an hour optimizing a feature because it felt slow - turns out that the slower simulated connection had just stayed enabled after a restart (can’t remember if it was just the browser or the OS, but I previously needed it and then later just forgot to turn it off). Good times, useful feature though!

Working as intended!

hahaha - I've done something similar. I had an automated vitest harness running and at one point it ended up leaving a bunch of zombie procs/threads just vampirically leeching the crap out of my resources.

I naturally assumed that it was my code that was the problem (because I'm often the programmer equivalent of the Seinfeld hipster doofus) and spent the next few hours optimizing the hell out of it. It turned out to be unnecessary but I'm kind of glad it forced me into that "profiling" mindset.

sounds like the MacOS network utility. I've been bit by leaving it on after testing ios apps :D

Imagine the speed of those optimizations once you turned it off. lol. Love it!

I wonder if that works beneficial on old computers that freeze up when you try load the GB js ad-auction circus news circus website. I want to browse loaded pages while the new tabs load. If the client just hangs for 2 min it gets boring fast.
