@tripplehelix Could you please provide the output of the command rustc --print cfg | grep target?

@tripplehelix Then, could you please run this tiny Rust program and provide its output?

fn main() {  
 println!("{:?}", std::thread::available_parallelism());  
}

Ok(16)

@mo8it Maybe the issue isn't that. Compiling barely uses any CPU and only ever hits one core hard. Maybe it's being limited by something.

@tripplehelix Looks good. Weird.

In Gnome, there is a setting for energy consumption for AMD CPUs. Make sure that you have the performance mode and not power saving.

@mo8it My computer is running in 'Desktop' mode was in 'Balanced' via tuned. But then I used balanced mode on the intel machine.

I run XFCE. Think this is going to be one of those issues that just surprises me and suddenly works properly.

@mo8it OK this seems to be a much more widespread issue, as even clamscan uses only 6% CPU.

Thanks for the help though!

@tripplehelix Compare Rust version and exact crate contents. Operating system shouldn't matter but can't be eliminated.

@dcz I've tried the stable rustup tool kit and nightly, both the same issue, currently have rustc 1.79.0-nightly.

The slow compile happens most glaringly with the eza and spotify_player crates, but also with alacritty.

Using Debian Sid, but I was also on Sid on Intel. My first thought was that it might be some issue with the t_64 transition. Maybe some packages are just struggling.

@tripplehelix I think you should dig more into the versions: it's not clear from what you wrote that you were actually using the same versions between builds - neither of rustc nor of the crates.
