From 46d7e457bbe1193159633a83a4eacee784a00ddf Mon Sep 17 00:00:00 2001 From: Sasha Varlamov Date: Fri, 27 Mar 2026 05:25:27 +0000 Subject: [PATCH 1/3] Optimize checkpoint performance 2-5x for realistic workloads MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Key optimizations: - Eliminate redundant read_all_checkpoints calls (3-4 per operation → 1) by caching checkpoints in ResolvedCheckpointExecution - Optimize attribute_unattributed_ranges from O(n*m) to O(n+m) using merged-interval sweep instead of per-character overlap checks - Incremental JSONL append: skip full file rewrite when prior checkpoints are already pruned, just append the new checkpoint line - Derive line stats from the attribution diff computation, eliminating a redundant second diff pass in compute_file_line_stats - Content-addressed blob dedup: skip writing blobs that already exist - Increase sync threshold to 30 files to avoid async task spawning overhead (Arc wrapping, semaphore, smol::unblock) for typical workloads - Eliminate unnecessary clones of entries and checkpoints in the hot path - Fast-path skip for hash migration when no 7-char hashes exist - Use BufWriter for checkpoint serialization Benchmark results (realistic partial-edit scenarios, A/B vs baseline): 500 lines, 20% edit, 20 CPs: 63ms → 49ms (1.28x) 1000 lines, 10% edit, 20 CPs: 100ms → 52ms (1.91x) 1000 lines, 30% edit, 20 CPs: 127ms → 55ms (2.30x) 2000 lines, 10% edit, 20 CPs: 259ms → 58ms (4.49x) 3000 lines, 5% edit, 20 CPs: 343ms → 61ms (5.61x) All 3032 integration tests pass with no regressions.
