Rust

I’ve seen people complaining about some gigantic C/C++/Rust projects engulfing all of their memory during building from time to time. Fortunately, there are a few simple methods to alleviate the pain without sacrificing speed. By “simple,” I mean you don’t have to modify your code! Root of the problem Usually, the most memory-consuming part of C/C++/Rust builds is the linking phase. To link object files, the linker must read all of them into memory....

Difftastic is a structural diff that understands syntax. The diff results it generates are very fancy, but its performance is poor, and it consumes a lot of memory. Recently, I boosted it by 4x while using only 23% of memory (#393, #395, #401). This post explains how I accomplished this. Hope it can bring you some inspiration. When I started to write this post, not all optimizations were reviewed and merged....
