⚡ Bolt: optimize concurrency with structs and sliding windows#66
Conversation
Refactored `CacheScanner` and `NodeModulesScanner` to `struct` to bypass actor executor bottleneck, enabling true parallel execution across threads for stateless operations. Changed `ProcessMemoryScanner.scanPIDs` to use a sliding window instead of static chunks, ensuring optimal throughput by keeping active tasks near the maximum allowed concurrency rather than waiting for entire chunks to finish.

💡 What:
CacheScannerandNodeModulesScannerfromactortostructProcessMemoryScanner.scanPIDsto use a sliding window with an iterator rather than breakingpidsinto statically sized chunks for the task group.🎯 Why:
actors run child tasks sequentially on a single executor due to context inheritance. Converting them to stateless structs allows parallel task execution for I/O bound scans.ProcessMemoryScannermeant a new chunk couldn't start until the slowest task in the current chunk finished (tail latency problem), leaving the thread pool underutilized. A sliding window keeps exactlymaxConcurrencytasks in flight at all times.📊 Impact:
🔬 Measurement:
ProcessMemoryScanner.scan(topN:)or the global scan over high-density node_modules projects and observe reduced total processing time compared to trunk.PR created automatically by Jules for task 14520363108491777627 started by @acebytes
