QuickChat making site very slow.

I am having the same issue. As soon as I add a chat room to a page, the site slows down to a crawl and becomes pretty much unuseable.

Up your memory limit. Write in wp-config.php file following code:

define(“WP_MEMORY_LIMIT”, 256);

It may not be enough. The more people who use your chat, the more taxing it’s going to be on the server. Maybe after you get just 30 users chatting simultaneously, it’s going to slow down again.
