perf: hot-path micro fixes in the render loop#403
Conversation
- _check_wifi_status_message stat'd the status file on every render iteration (60+ fps) for a message whose lifetime is seconds; throttle the check to 1 Hz with a cached result. - Demote the per-iteration "Display active, processing mode" INFO to DEBUG and convert the remaining eager f-string logs to lazy % args — the devpi baseline showed ~9 journald lines/sec, which is both noise and SD-card wear. - Vegas cycle-end blank frame: hoist the inline PIL import and reuse a preallocated buffer instead of allocating per cycle wrap.

How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Summary
PR 3 of the performance series. Three small render-loop wins:
_check_wifi_status_messageran a filesystemexists()at frame rate (60+/sec) for an overlay message whose lifetime is measured in seconds. Result cached within the window."Display active, processing mode"INFO is now DEBUG, and the remaining eager f-string logs in the mode path are lazy%-style. Baseline on the devpi measured ~9 journal lines/sec — that's log I/O + SD wear for nothing.from PIL import Imageand a fresh allocation per scroll-cycle wrap replaced with a reused, re-blacked buffer.Explicitly deferred (per plan): scroll_helper's per-frame frombytes/tobytes allocation.
Verification
195 display/vegas/controller tests pass. Devpi journal-rate re-measurement to follow with the series deploy.
