Hey there - we've tried using your chat plugin on our site but had some issues running it. We had about 12,000 users on at once during launch and it caused our server to shut down wordpress's AJAX handler "admin-ajax" (12k x 1 hit every 1 sec). We're using WP-Engine's business package. The chat was also super slow.
But this polling is to be expected from a chat plugin as the chat needs to be live and interactive. Do you know of any strategies to workaround this overloading issue?
Perhaps an on/off switch functionality attached to running the chat to limit those hits?
