“Checksumming the dependencies in the Gemfile may help.”
“Bundler now supports cooldown”
“I'm not super familiar with Bundler's architecture”
I wrote some code to do almost this many years ago (if I recall correctly, it doesn’t cache anything to disk, but builds the hash fresh each time, which can still result in massive speed up). Probably obsolete and broken by now, but one of my favorite mini projects. (And I just realized the svg graph is all but impossible to read in dark mode) https://github.com/pmahoney/fastup
What I would do to really squeeze the rest out in pure ruby (bear in mind I’ve been away about a decade so there _might be_ new bits but nothing meaningful as far as I know): Use a cheaper to parse index format (the gists I wrote years ago cover this: https://gist.github.com/raggi/4957402) Use threads for the initial archive downloads (this is just io, and you want to reuse some caches like the index) Use a few forks
“global cache for all bundler instances”

I use it quite a bit when I have to monkeypatch a gem to backport a fix while I wait for a release: raise "check if monkeypatch in #{__FILE__} is still needed" if Gem::Version.new(Rails.version) >= Gem::Version.new("8.0.0") This will blow up immediately when the gem gets upgraded, so we can see if we still need it, instead of it laying around in wait to cause a subtle bug in the future.
