-Subject: [PATCH 11/11] perf: cache UAZoomEnabled() and rate-limit completion
- tracking
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-UAZoomEnabled() performs a synchronous Mach IPC roundtrip to the macOS
-Accessibility server (~50-200 µs per call).  With three call sites in
-the redisplay hot path (ns_draw_window_cursor, ns_update_end fallback,
-ns_zoom_track_completion) this adds up to 150-600 µs of IPC overhead
-per redisplay cycle.  At 60 fps, that is 9-36 ms/s of pure IPC cost.
-The overhead blocks the main thread, extending the inter-frame interval
-and making cursor movement feel choppy, especially at the end of large
-files where Emacs's own redisplay work is already at its maximum.
-
-* src/nsterm.m (ns_zoom_cached_enabled, ns_zoom_cache_time): New
-static variables.
-(ns_zoom_enabled_p): New inline wrapper around UAZoomEnabled().
-Caches the result for 1 second using CFAbsoluteTimeGetCurrent(), a
-near-free VDSO call.  Zoom state changes only on explicit user action
-in System Settings, so a 1-second TTL is indistinguishable from
-querying on every frame.  Replaces all three UAZoomEnabled() call
-sites.
-(ns_zoom_track_completion): Add 500 ms rate limit.  Completion
-candidate detection requires FOR_EACH_FRAME iteration and
-Fget_char_property calls.  Completion state changes at human
-interaction speed (well below 2 Hz), so 500 ms polling is
-imperceptible while eliminating per-redisplay Lisp overhead.
