Chat delay

well... when me and my friends play at our realm, the chat is always delay, we cant communicate when needed, like 1 hour ago my friend was about to die and chatted saying "HELP" but we didnt see the chat because its delay... PLEASE FIX THIS its been like this for a long time, its fine if the delay is just 30 seconds but IT LASTS A FEW MINUTES, SO PLEASEEE FIX THIS....
