# [Plugin: Related Posts Thumbnails] Optimized performance

 * I love this plugin but lately I had to turn it off because of performance. I 
   have a site with over 45k unique visitors a day and over 100k pages viewed daily.
 * The plugin is set to show 12 thumbs with “tags” as the relationship. My server
   load shot up to an average 15.00 compared to 1.3.
 * I think W3 Total Cache is not chaching the related thumbs hence my server load.
 * Is there a way to check if the related thumbnails are being cached?

 * Performance is also an issue with a couple of my sites. We have over 22000 articles
   on one site, and we’ve only got it set to show 3 related posts, using tags and
   categories. I’ve tuned the settings down to only include posts after Jan 1 2008,
   but it still hasn’t helped much.
 * Not using a caching plugin, but looking at the SQL query being generated, that’s
   a crazy query:
 * SELECT distinct ID FROM wp_posts WHERE post_type = ‘post’ AND post_status = ‘
   publish’ AND ID<>19714 AND post_date >= ‘2008-01-01’ AND ID IN (obnoxiously long
   list of nearly 15000 individual post IDs) ORDER BY rand() LIMIT 3;
 * I’ve seen that query take anywhere from 3 to 25 seconds. Not good.
 * I’m open to a solution, because I also love this plugin. Adore it, even.
