⚡ Bolt: Optimize ProcessMemoryScanner concurrency with sliding window#86
Conversation
In `scanPIDs`, replace static array chunking with a continuous iterator-based sliding window inside `withTaskGroup`. This avoids tail-latency waiting where the system idles waiting for the slowest task in a chunk to finish before starting the next chunk, maximizing throughput when scanning hundreds of PIDs concurrently.

💡 What:
Replaced the static array chunking in
ProcessMemoryScanner.scanPIDswith an iterator-based sliding window approach insidewithTaskGroup.🎯 Why:
Static chunking limits throughput due to tail latency — the system has to wait for the slowest task in a chunk to finish before starting the next batch of tasks. A sliding window with an iterator maintains maximum concurrent execution limits continuously, keeping all worker "slots" full as long as there are PIDs left to scan.
📊 Impact:
Improves the throughput of process memory scanning by avoiding idle waiting. This reduces the overall time taken to scan all PIDs, especially when scanning hundreds of processes with varying completion times.
🔬 Measurement:
Run the app and observe the process scanning speed. The difference is most notable on systems with many running processes.
