A lot of PHP Requests Slowing Down Site

Please, I’d like to report some issues with your plugin DW Question and Answer. It makes a LOT of requests to the server and makes the site to crawl. Each PHP request takes over 20 minutes to load, which is a huge load on the server. I have had to deactivate the plugin until we are able to get a fix for this. Please look into it and help out. I am sure other users will be having the same issue. Thank you
