Thanks for the link! I knew about strip, which helps a lot, but the other options look promising as well.

I really care about binary size, since for short running programs, or when startup latency is important it can actually be much faster in real time to have less, but slower code. Especially so on a slow HDD like in my laptop. Loading a few MB when it's under heavy load can take a few seconds.

Edit: Wow, LTO makes a huge difference. Almost a 40% smaller in my case AND it's faster. Really excited to try xargo now.
