Wait, someone actually cares about performance these days? I'm not sarcastic here, this was a really cool read evocative of Raymond Chen and the old NT Debugging blog.
I'd like to read more blogs where the solution to bad performance isn't just 1) throw more servers at the issue 2) rewrite the service in a different language / framework and hope to not hit the same pathological case again.

- stefan_ 6y agoMaking sure surfaces aren't copied needlessly is actually a rather common optimization, and particularly so on mobile devices where great care is taken that all subsystems can share memory - e.g. the display silicon needs to be able to use textures from the video decoding directly for scanout. Not doing so escalates quickly - copying a 4k10bpp buffer 60 times per second takes up ~5Gbit of memory bandwidth.
- brundolf 6y agoPerformance is incredibly important in web browsers - almost as important as the system itself, but it's a much younger domain so there's more left to be figured out. Chromium and Firefox regularly generate some of the coolest and most interesting optimization-related blog posts out there.
