[WP Smush Pro] Conflict with another plugin

We've been using YoImages for cropping image sizes. This plugin by itself takes 2 to 3 seconds to make a crop. When WP Smush Pro is installed, making a crop takes up to 30 seconds.

Might this be a conflict between WP Smush Pro and YoImages? Is there something we can do to reduce those 30 seconds?

Hope to hear from you, thanks in advance!
