I find these optimizations fascinating. Anyone familiar with Lemire likely knows about this, but I listened to a podcast episode[1] with him a few days ago and learned about `simdjson`, the tool he authored that parses JSON at 25x the speed of the standard C++ library.[2][3] It's worth looking at if you're into this sort of thing.

If so, Ive been following it for a couple years, but I put it out of my mind recently after moving to AMD. I could sware it was an intel only project, but a quick scan of the that git suggests I'm wrong. So either I'm totally missremembering, or AMD support was added later.
Anyway, I cant wait to try that out again. I wonder why most projects don't just use this as their default json parser now?
