Computer hardware and compilers have evolved hugely, which means that many of the guidelines for writing performant code are now obsolete. ‘Big O’ complexity (a key tool in understanding performance) is often misunderstood - advances in CPU design have changed performance parameters beyond recognition. The range of available tools and techniques can be overwhelming.

This talk focus on general issues, with some focus on Rust-specifics. We go through in background, computer architecture, benchmark and profiling, optimisation and performance rust.
