I'm not sure if this file should be checked in, because it requires rust nightly, and the threads is specific to your machine. But it did speed up compilation a LOT.

Besides the impact on compilation speed, do these changes affect the performace of the compiled code like speed or binary size?

The debug and lto aren't real changes (just using different names for the same thing), but the panic abort is supposed to increase performance.

This had the biggest performance benefit while developing, but unfortunately can't be used for lemmy builds or CI. Not sure what the best way to handle this would be.
Maybe just provide this in the development instructions only? Not sure.

devandreleaseprofiles.This greatly speeded up my compilation times.
