Turns out creating the relevant indexes helps a lot, unsurprisingly I guess: https://git.savannah.gnu.org/cgit/guix/guix-cuirass.git/commit/?id=db27955ad3fae260ee2aa4bace8dd6a4115d338c I also discovered SQLite’s “EXPLAIN QUERY PLAN”, which is pretty cool: https://www.sqlite.org/lang_explain.html With that /latestbuilds still usually takes a bit more than 2 seconds. This could be due to the repeated ‘Outputs’ queries via ‘db-get-outputs’. Ludo’.
