I was trying to setup profiling in nix using this[1] to figure out why colmena is slower, but didn't quite succeed (I think I got a -ENOSPC or something due to /tmp/ as tmpfs or something). Do you think something like this would be useful to debug this performance behaviour?

Yeah, I think something like this is useful in general, not just for colmena but for nixpkgs slowness as well

@zhaofeng:zhaofeng.liZhaofeng LiAlso the issue I linked above has a list of commands that correspond to what Colmena actually evaluates underneath, so you can manually invoke the same evaluation in the profiler16:04:25
