From 0ae3b3a9225a87e5a136f6998de616a103295491 Mon Sep 17 00:00:00 2001 From: sukuwc Date: Mon, 1 Jun 2026 17:08:59 +0200 Subject: [PATCH 1/2] SUKU batch user_input store updates via requestAnimationFrame MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Incoming serial EVENT messages were triggering synchronous Svelte re-renders across 14 subscriber components on every hardware event, costing 5–20ms per message on the main thread. Introduce RAF batching in process_incoming_event_from_grid: computed values are staged in a plain JS field and flushed to the store once per animation frame, decoupling the serial ingestion rate from the render rate.
