The problem with this plugin

http://wordpress.org/plugins/yet-another-related-posts-plugin/

is that my page load time will go from 3:00 seconds up to 4:76 seconds after installing this pluggin. Do you know of one plugin that doesn`t change so much de page load time

Strange, I tested on my site and the load time is 2.69 without the plugin and 2.75 with the plugin.

In 2008 our "friend" Matt Cutts wrote a post where he suggested 5 plugins, I am not sure how relevant those plugins are after so many is years, but is worth a try.
