# NousResearch/hermes-agent · macOS proxy probe and I/O performance improvements

## Open now

- Nothing open on GitHub.

These items address performance overhead in the gateway on macOS, specifically the cost of forking scutil on every outbound chunk for system-proxy detection and moving file I/O and per-message scans off the event loop.

## TL;DR

- 3 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 1 PR(s) closed without merging.
- A fix was merged to main in PR #120405. Verify it addresses your case.
- **Recommended:** read PR #120405 (and any competing PRs below) before filing. Confirm the merged change covers your symptom.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `resolved` · deciding PR(s): `pr-120405`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.67`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.

## Closed / duplicate issues

- #117959: macOS system-proxy probe forks scutil on every outbound chunk (~11 ms each)
