The useful No Ping Wait WordPress plugin was created by by Robert Deaton, but due to an apparent hardware failure he lost his entire site.
The purpose of the No Ping Wait plugin is to prevent WordPress authors from having to wait for all of the update services to respond to new post pings. You may have noticed that when you actually “publish” a post there can be a delay as long as a minute or more. This plugin solves that problem by moving generic pings to execute-pings.php.
I highly recommend this plugin and you can download it here.
