9056 :: Did nimc become faster?

  Devel branch user here. I noticed that the compilation process became noticeable faster. In some tests this has become x2 as fast. Have programmed much in nim since december tho. Is my impression wrong?

  Your stable branch Nim compiler binaries may only be compiled with -d:release while devel compiler might be compiled with -d:danger/--gc:orc etc. Beyond that I don't know what change could have caused a performance increase, though I feel like I may have come across it recently trying out the devel compiler.

  I haven't followed new commits in the Nim repo lately, but I think I haven't seen any PRs that result in big changes to compile times except maybe https://github.com/nim-lang/Nim/pull/19578 which might help you a lot if you have macros-heavy code.

  It is worth investigating in case it happened as an accident.

  To make that a lot easier it would be nice if you could share your pre and post versions. It could also be that your previous devel had a performance regression in it

  I've been using devel for years. If I have some time I'll post a real comparison. Maybe I'm just fooling myself.
