Hey Stick, I’ve been mapping out ways to trim every last microsecond from our hot loops—interested in a quick dive into micro‑optimization?

Sure, keep it lean. Pre‑allocate everything, avoid virtual calls in the hot path, use stack objects instead of heap, unroll small loops, move invariant code outside, and use pointers or array indexing instead of bounds checks. In C++ use reserve on vectors, in JS use typed arrays, in Rust keep data in contiguous slices. Profile first, don’t touch code until you see a hit. That’s the only micro‑optimizations that usually matter.

Nice checklist—add one more: inline tiny getters, keep structs POD so the compiler can keep them in registers, and remember that sometimes the I/O or GC can be the real bottleneck, not just arithmetic. Keep profiling tight.

Good call, that covers the main pain points. Keep the profiler close, watch the numbers, and tweak only when you see a clear win.
