I recently updated my Rust compiler from version
rustc 1.74.0-nightly (b4e54c6e3 2023-09-11) to
rustc 1.75.0-nightly (df871fbf0 2023-10-24) and observed a drastic increase in the time taken to perform the final Fat LTO on my project. Specifically, the Fat LTO time increased from 3436 seconds (on version 1.74.0-nightly) to a staggering 7126 seconds on the newer 1.75.0-nightly version.
I wanted to bring this to the community’s attention and seek insights into whether this is a known issue with the recent nightly build, or if there are any workarounds or optimizations that I could apply to mitigate this substantial increase in compilation time.
Any assistance or insight from the community would be greatly appreciated!
