PROPOSAL ONLY - Do not merge
This PR removes a semaphore that actually serialized all access to the
Add()
,Push()
andPushUntrusted()
methods inchain/messagepool
so that only one goroutine thread can run it at once.This semaphore may have be contributing to the high latency spikes we see on the glif nodes
These methods already have a mutex guarding critical sections, but the question is whether its needed when publishing message to topics (which I guess can take a while since it calls out to libp2p and other peers).
