Has anybody else noticed build performance regressions with the Rust version released last week? We are seeing 2x build times for release builds.
You can report a bug.
Yes, I will, but I wanted to feel the pulse here first before bothering making a reproducible example out of it.
Thank you for the report, I will skip the release then.
A good place to start looking is rustc performance data.
Tip: The "dashboard" is often a good first place to check.
(The absence of a slowdown in those pages doesn't mean there aren't any regressions, it just means it's unlikely to be systemic).
LOL, you were not going to use it anyway. Don't you stay back in time, version wise.
Can you give more information on your setup?
I tried to reproduce your issue, but I'm seeing almost identical compile times between version 1.95.0 and 1.96.0. My host is x86_64-unknown-linux-gnu and target aarch64-unknown-linux-gnu, and I'm testing on a workspace that compiles in about 5.9 seconds with the default release profile.
