CPU profiling a containerboot subnet router on a large tailnet showed roughly 40% of CPU spent in serveWatchIPNBus JSON-encoding the full netmap on every update. containerboot only reads SelfNode fields from those notifications (and does a peer lookup when TailnetTargetFQDN is set), so it does not need every intermediate netmap delta. Set ipn.NotifyRateLimit on all three WatchIPNBus calls so netmap notifications are coalesced to one per 3s. Initial-state delivery is unaffected since the rateLimitingBusSender flushes the first send immediately. Updates #cleanup Signed-off-by: Doug Bryant <dougbryant@anthropic.com> |
