arcanine

mjm.atticd.enable = true;

arcanine runs atticd, a binary cache server for Nix. I use this server to cache the artifacts I build for all of my machines so that I avoid needing to rebuild things for no reason.

microvm.vcpu = 4;
microvm.mem = 2560;

arcanine uses a few additional CPUs and increased RAM. The load attic needs to handle is very bursty, so these resources can feel excessive, but they are helpful for handling many requests at once, since those requests are inevitably streaming large files.
