Inconsistent latency sending data to client
I have 3 websocket servers running on the same hardware. When a message request comes in (onMessage), all 3 take less than 0.03s to process the the message from the client and create the correct response. However, as measured by Firefox/Chrome web inspector tools, one client gets its response in less than 200ms and the other two clients take 400+ms to get their responses. I am using the same computer to test, so server->client latency is consistent. The delay happens somewhere after the server interface class executes the ConnectionInterface $client->send command.

I am utilizing the uv extension for all three websocket servers (ExtUvLoop class)

I have no idea how to begin to troubleshoot this problem. Any advice on how to begin would be greatly appreciated.
