⚡ Bolt: [ProcessMemoryScanner concurrency optimization]#71
Conversation
- Replaced static chunking of PIDs with an iterator-based sliding window. - Eliminates tail latency where the task group had to wait for the slowest task in a chunk to complete before starting new tasks. - Maximizes throughput by keeping the active task count continuously at `maxConcurrency`.

💡 What:
Replaced static chunking in
ProcessMemoryScanner.scanPIDswith an iterator-based sliding window approach. It usespids.makeIterator()to keep exactlymaxConcurrencytasks running at all times.🎯 Why:
The previous implementation grouped PIDs into static arrays (chunks) and awaited the entire group. If one
proc_pid_rusagecall was slow, the remaining available concurrency slots would sit idle until that slowest task finished, causing tail latency.📊 Impact:
Maximized concurrency throughput. When scanning hundreds of PIDs, this ensures the scanner finishes faster by eliminating idle wait times within chunks.
🔬 Measurement:
Review the refactored
scanPIDsmethod to verify it now enqueues a new task immediately as eachawait group.next()returns, rather than chunking.PR created automatically by Jules for task 17083400779117850752 started by @acebytes
