      Even with a couple thousands of files, you are usually still subsecond in fs time. But that can matter! Total parse time doesn't differ much

      Memory usage can be lower, but the bundler framework matters here. Preprocessing like minify+constant fold saves more parse/mem in my exp

      Like @jdalton did with his .gz loading, the cost of *reading* files can be prohibitive if your disk is slower/cpu is fast enough

      What nobody's answering for me: what is the perf for all node code bundled into single bundle vs w/o

      Correct. I've seen native module reso times cut down considerably for webpack by bundling webpack and running it. But didn't know nuance lvl

      I think generally if you can get away with bundling reliably you'll get wins, but caveats:

      1. During dev mode, when lots of things are changing, the bundling time can swamp the wins.

      2. Before ES2015 modules, it's difficult to reliably bundle, so your bundled modules will often fail without manual intervention.

      3. (2a?) Patterns like "load all my tests" are trickier in module world.

          TLDR: if you bundle your modules, you'll hit all the caveats you hit when trying to bundle node modules for the browser.

          We have a good excuse to deal with the limitations when bundling for the browser, but less good excuse when you have actual node.

          I think this calculus changes with es2015 modules, but we're a while away from bundles composed entirely of es2015 source.

          I think even with JS modules the bundling will be a worse dev experience. E.g. having to deal with source maps.

          The ecosystem is just not good at pipelines that produce reliable source maps. We gotta fix that.

          A standout: TypeScript. Their sourcemaps are delightful.

          Lol we need a sourcemap spec. Not just a gdoc. Not down playing the work. But implying a revisit strongly needed to be etched in W3C tablets
