## Issue Addressed Some nodes not following head, high CPU usage and HTTP API delays ## Proposed Changes Patches gossipsub. Gossipsub was using an `lru_time_cache` to check for duplicates. This contained an `O(N)` lookup for every gossipsub message to update the time cache. This was causing high cpu usage and blocking network threads. This PR introduces a custom cache without `O(N)` inserts. This also adds built in safety mechanisms to prevent gossipsub from excessively retrying connections upon failure. A maximum limit is set after which we disconnect from the node from too many failed substream connections.
