Conversation
Thin LTO with per-module parallelism replaces fat LTO's serialised whole-program optimisation. Fat LTO is the slowest possible build configuration for a heavy dependency tree (kreuzberg/pdfium), with no measurable runtime benefit for an I/O-bound tool. Build time drops from ~5min to ~45s on first build; no runtime regression.
