Limits of gulp.watch debounce delay when running accessibility linting tasks

The goal is to configure gulp.watch so that accessibility‑linting tasks (e.g., axe‑core, eslint‑plugin‑jsx‑a11y) receive timely feedback on file changes while avoiding unnecessary CPU spikes.

Because gulp.watch applies a single debounce delay to all matched globs, lowering the delay to improve responsiveness can cause the linting tasks to run excessively, increasing CPU load and risking race conditions, whereas raising the delay reduces CPU usage but may introduce perceptible latency in the accessibility feedback loop.

The delay option is documented, but there is no built‑in mechanism to assign different delays to individual watchers within the same gulp.watch call, and older Node.js releases (<10) may alter timer resolution, making the effective debounce behavior less predictable.

What delay value provides a practical balance between low latency and acceptable CPU usage for accessibility linting? How can teams evaluate the impact of different delay settings on their specific workflow without introducing per‑glob complexity? Are there recommended patterns for separating watchers when distinct debounce behavior is needed?
