perf(nav): disable eager prefetch on site-wide nav links - #268
Merged
Conversation
The nav pill renders on every page, so Next's default Link prefetch fired
an RSC request for each nav route (/deck, /globe, /resources, /) on load.
A burst of those concurrent server renders saturated the Worker isolate,
surfacing as "exceeded CPU time limit" across all routes for ~1s (static
assets included) before recovering. Set prefetch={false} on the desktop
nav links, logo, submit CTA, and mobile-menu links so routes are fetched
on hover/tap instead of eagerly on load.

Summary
Worker exceeded CPU time limitburst seen in production (all routes, including the static/icon.svg, failed for ~1s then recovered).<Link>prefetch fired an RSC request for each nav route (/deck,/globe,/resources,/) on load. A burst of those concurrent server renders saturated the Worker isolate.prefetch={false}on the desktop nav links, logo, submit CTA, and mobile-menu links. Navigation still works (Next fetches on hover/tap); only the eager on-load fan-out is removed.Notes
