| A doc opens at once: the page carries the document's saved state, so the editor mounts without waiting for its live room, which connects in the background and sends only what changed, with a quiet dot that turns green when it's synced; edits made before then are kept and sent once. The editor's code is preloaded from the page and fetched early when you hover a doc, the app's shared code ships in a few chunks instead of a hundred small ones, socket tickets come with the page instead of a round trip, and the artifacts service answers a page, a sidebar and a room in parallel lookups instead of a dozen in a row, reporting its database round trips in Server-Timing. The artifacts guide says how a doc opens, and CONTRIBUTING's Speed section has the numbers. | 1 | -- The document itself, saved beside its text rendition each time a folio's |
