Speeds up rebuilds by caching
“tools like sccache can dramatically reduce rebuild times by caching artifacts”
Comment from 11 May 2026 in “CUDA-oxide: Nvidia's official Rust to CUDA compiler” “use sccache in ci to cut down on compile times”
Comment from 27 Oct 2026 in “One year of Dioxus fullstack in production: the good, the painful” “sccache for crate compilation caching”
Comment from 13 Jun 2026 in “The state of building user interfaces in Rust” Used in CI and shared builds
“If you give it another go, I would recommend a shared sccache.”

Comment from 27 Oct 2026 in “One year of Dioxus fullstack in production: the good, the painful” Seen as a baseline setup
“You should have set up https://github.com/mozilla/sccache at minimum.”

What people warn about
Each mark is one comment
Cache misses still recompile crates
“even when I setup sccache for our team and our cache hit rate remained below 20%”
Comment from 9 Jul 2026 in “Rewriting Bun in Rust” “Even that doesn't fully avoid recompilation of the same crate”
Comment from 1 Oct 2026 in “How to speed up the Rust compiler in September 2026” Slow compiles and caching overhead
“Even with sscache the compile times are not great”
Comment from 26 May 2026 in “Performance of Rust Language [pdf]” “caching jobs took longer than some build steps”
Comment from 27 Oct 2026 in “One year of Dioxus fullstack in production: the good, the painful” Poor scaling and capped parallel jobs
“there's a hard cap on parallel jobs”
Comment from 6 Mar 2026 in “Tech employment now significantly worse than the 2008 or 2020 recessions” “find it doesn't scale well”
