Time brew install imagemagick bat feh python mruby I decided to re-run the brew install command, but skip Crystal, which only took a few more seconds: => Installing crystal dependency: Pouring Too many open files rb_sysopen - in 600.02 secs fish external Time brew install imagemagick bat feh crystal python mruby Prior to that, though, installation crashed because of a ulimits issue when ‘pouring the bottle’ for LLVM: Apparently there's no bottle for Crystal, so it took a very long time to install because it had to compile from source. So instead, I selected a handful of packages from the Linux formulas list that I figured would pull in a substantive dependency closure. It seems that GUI apps (Libreoffice, Firefox, etc.) tend to be packaged exclusively as casks for Homebrew, which means they don't exist on Linux. I had some trouble looking for large packages to install with Homebrew and Nix for comparison. Time nix search nixpkgs libreoffice >/dev/null Homebrew takes about twice as long to search for packages related to Libreoffice (results omitted to HN won't tell me this post is too long):

Sys time 4.72 millis 283.00 micros 4.43 millis Interestingly, Homebrew is using ~2x as much disk space, and listing my installed packages (none) with Homebrew takes ~30x as long as with Nix: To make it fair, I've removed almost everything I have installed with Nix, as well as Homebrew. Now that I'm on my Ubuntu system, I can easily test Nix and Homebrew side-by-side. Tl dr: Homebrew actually takes several times as long to install packages as Nix does, and uses up way more space despite a less isolated toolchain.
