Folding Space and Time
summary
Claims concrete wins: bundling plus uglify cuts boot time roughly in half; pkg binaries package Node with a runtime and yields about a 20% faster start in v4; precompilation (prepack, Babel plugins) folds constants and compiles markdown to JSX ahead of time; the app prefetches code and data to make UI actions feel immediate; search uses a newline‑delimited streaming protocol to stream partial results; APIs are deployed via DNS anycast (San Francisco, Brussels ~40ms) to reduce latency.
