Slow loading with load of WP_Query

Hi,

After enabled the plugin my site got really slow loading (just front end, back end still fast as normal) so I installed Query Monitor plugin to see what going on.

As expected, it caused by new installed Plugin: related-posts-for-wp

There is a lots of query like that on home and archive pages, each take 0.5 – 0.6s which caused the page take 15 – 20s to load. There is 1 query like that on single page which add 0.6s extra!

Hope you can look into this.

Thanks.
