Jacob Wujciak-Jens commented on ARROW-17872:
--------------------------------------------

bq. 10 minutes for extracting 1.5GB seems quite unexpected

I have checked in detail and each of the bigger dependecies (aws, llvm, boost) 
take 2-3 minutes to "pour", so ok speeds I would say. Just over all a lot but 
still nothing  Isee the cache really speeding up. 

The timeout is set to 60 minutes so we could just raise that limit if it is not 
 applicable for the current build complexity (or as you said remove features). 
The build should already be using all 3 available cores.

> Our macOS CI builds on Github Actions usually take at least 10 minutes 
> installing dependencies from Homebrew (because of compiling from source?). It 
> would be nice to cache those, especially as they probably don't change often.
