Got myself a few months ago into the optimization rabbit hole as I had a slow quant finance library to take care of, and for now my most successful optimizations are using local memory allocators (see my C++ post, I also played with mimalloc which helped but custom local memory allocators are even better) and rethinking class layouts in a more "data-oriented" way (mostly going from array-of-structs to struct-of-arrays layouts whenever it's more advantageous to do so, see for example this talk).

What are some of your preferred optimizations that yielded sizeable gains in speed and/or memory usage? I realize that many optimizations aren't necessarily specific to any given language so I'm asking in [email protected].

Surely you got a bonus and a raise out of it right? Right??

Who am I kidding only managers get such things

The only reward I got from it was recognition from my team members, which was already more than what I was expecting to get.

My manager was praised for the higher team velocity and improvements in the team's burndown chart. The hallmark of having done good work is seeing others trying to take credit for it.
