Hello! I was looking at the “history chart” at <http://hydra.nixos.org/build/2517280#tabs-history>, which shows graphs of the build time and installed Guile size vs. commits. Timings must be taken with a grain of salt, because of variability on the build machines.
Still, a couple of worthwhile observations: • commit 1af6d2a (“Minimize size of embedded syntax objects in psyntax-pp.scm”) reduced the installed size from ~14.6 MiB to ~13.3 MiB; • CSE led to a build time increase from 28m at <http://hydra.nixos.org/build/2413477> to 43m <http://hydra.nixos.org/build/2478518>. Thanks, Ludo’.
