Next.js: Build Scale Wins and Cache Reliability Fixes
Turbopack and build performance dominate with faster static checks and chunk merging for large apps, alongside a fix for hanging responses after use-cache errors. Export memory crashes and redundant scheduler work were also addressed.

Good morning, it's October 26th, 2026, and this is your Next.js daily briefing.
Today's through-line is building bigger without breaking: the team chased down build-time bottlenecks that only show up at thousands of pages, and closed holes where caching could hang or crash a build.
First, build speed. A fix in pull request 100615 removes a quadratic scan during the static check phase, replacing a per-page search over every route with a single index built once. On a three-thousand-page benchmark app, static check dropped from about four-point-three seconds to under two seconds, with identical…
Related work in Turbopack's merged-modules calculation, pull requests 100237 and 100238, parallelizes how chunk-group lists are merged and skips redundant reconciliation work. Together with its parent change, that phase fell from around six-point-six seconds to about one-point-eight seconds on the same large app,…
Underneath that, pull request 99764 trims overhead in the task scheduler by updating leaf-distance inline instead of re-locking, and pull request 100048 fixes a scale crash in static export: worker batches now get only their own resume-data seeds, avoiding a message that could exceed…
