Speed of compiling deno from source

Probably a dumb question but when building deno once getting towards the end (

Compiling deno v2.0.0 (/build/source/cli)

Compiling deno v2.0.0 (/build/source/cli)

) it ends up being stuck on 2 threads, fairly low CPU usage, high memory usage, working a long time. Is that unavoidable, just linking or something, or can I improve things?

(Platform: x86_64 linux but also curious about other platforms)

hmm where is the original text I put for this question... am I blind?

I see it in the main #help list...

I managed to copy it just incase others can't see it here:

Some more background: I have a pretty decent rig tackling this with 32 cores, I get through most of it really quick but hanging at the final phase for a long time means the total build took 11 minutes 13 seconds building deno v2

Yes, it's linking and it takes a very long time. You can expect anywhere from 5 to 20 minutes

Thanks for the reply. I've marked this as solved.

I know the aarch64-darwin build mentions in the rust flags.
Has anyone tried on other platforms or tried or at all?

@divy has been using on linux for good speed ups
