Hey guys, just wanted to kick off a thread about boosting compilation speed for C++ projects. I've been working on a large-scale project and noticed a significant slowdown in compilation times as the codebase grew. Looking for advice on optimal practices, any gotchas to avoid, and tools that can help squeeze out extra speed.

"Yup, using parallel builds with `-jX` flag can be a game-changer for large projects. It's also worth noting that setting `CXXFLAGS` to include `-O2` or `-O3` can give a nice speed boost, too. Anyone else have any other tricks up their sleeve?"
"Hey guys, I've found that disabling debug symbols in my Makefile or CMake config can significantly speed up build times. Also, have you tried using profile-guided optimization (PGO)? It can give some nice performance boosts, but requires a separate compilation and instrumentation step beforehand."

"Hey OP, just wanted to chime in on this thread. I've had great success with enabling multi-threading in my C++ compilation process using `-j4` with GCC. It's made a huge difference in cutting down my build times, especially on multi-core systems."
