Rust 1.90 Switching To LLD Linker On Linux For Faster Linking Times
With the Rust 1.90 release due out in mid-September, the Rust compiler on Linux x86_64 will begun using the LLD linker by default in order to 'significantly reduce' linking times.
In tests carried out by Rust developers, the linker performance can improve by as much as 7x and in the case of ripgrep yielded a 40% reduction in the end-to-end compilation time. There should be faster build times for most Rust programs and the hope is there will be no issues coming up in practice. Should anything bad turn up, LLD can still be disabled to fallback to the default system linker like GNU ld.
