From 06ab10cc37c8a4b586c6b7c9c9368157009e630c Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Wed, 18 Feb 2026 20:47:03 +0000 Subject: [PATCH 1/2] Optimize file search with concurrent fetching Refactored `FileIndexManager::search_files` to fetch file contents concurrently using `futures::future::join_all`, replacing the sequential loop. This significantly reduces the total time for search operations involving multiple files. Added a performance benchmark test `src/tests/file_indexer_perf_test.rs` which demonstrates a speedup from ~518ms to ~110ms for 5 files with 100ms latency.
