Use of server resources

Hi,

I used to use Contextual Related Posts plugin but it was overloading my server. I’d like to know if it is possible to use pro version to show only internal related posts.

Besides this I’ve read that you have “YARPP Experiments” plugin designer for high visited sites, but I didn’t find it in the wordpress repository.

Thanks
