"The difference between these two flows is subtle but staggering. Building my blog's backend with the old flow could take up to 10 minutes. Building my blog's backend with Earthly takes tens of seconds. The old flow produced a 734 MB image with a bunch of extraneous dependencies (even though that should be mathematically impossible). The new flow shits out a 262 MB image that has only what is required to run the blog."
