Description

Problem Statement:

When using find mode (/) on large web pages, searching is slow to the point of unusable.
Reproducible via https://nix-community.github.io/home-manager/options.xhtml.

Planned Improvements:
  • Delay / debounce FindMode.findInPlace() to reduce the frequency of searches during typing.
  • Implement a caching mechanism for text nodes, potentially using SimpleCache from ./lib/utils.js.
  • Offload text searching to a Web Worker or run asynchronously, possibly utilizing AsyncDataFetcher from ./lib/utils.js.
Expected Benefits:
  • Improved responsiveness during rapid typing in find mode.
  • Faster search performance, especially on large web pages.
  • Reduced strain on system resources during find operations.

Research direction

Start by reviewing FindMode.findInPlace() and the in-review PR #4547 for the debounce work. Then inspect SimpleCache and AsyncDataFetcher in ./lib/utils.js, and reproduce the slowdown on the linked Home Manager options page. Done means find mode remains responsive on large pages and the planned search improvements are implemented and verified.
