Partially Zoneless Performance tuning without big bang refactoring
summary
Claims a practical path to faster Angular apps: use RX Angular and template directives like partial zoneless templates (rxLet / rxIf / rxFor) to confine change detection to tiny embedded views, wire component state with connect to handle observables, and enable concurrent rendering with frame budget to eliminate long tasks. Demonstrations show drastic flame‑chart improvement, no frame drops, and a working app. You can then drop Zone.js with a remove Zone.js one‑liner after handling router change detection.
