The coming refactors and fixes change sync code, and a slowdown must be seen and explained in the commit that causes it. A JVM benchmark now times component sync on fixed-size worlds: - one main into 10, 100 and 1000 copies; - a change in the deepest of three nesting levels; - a chain of dependents (a in b in c, with copies of each); - a variant switch in a main with 100 copies; - a library update into a file with 500 copies. Each world is built once; only the sync an edit causes is timed, run to a fixpoint as the frontend watcher does. Each checks its result, so a world that synced nothing fails instead of timing nothing. `scripts/bench-components record` writes the baseline, recorded here on the code before this commit; `scripts/bench-components` compares against it and exits 1 when a world is more than 10% slower. It compares the lower quantile: with the devenv running, the mean of the same code moved from 0.41 to 1.13 of the baseline, the lower quantile by under 12%.
