Site loading impact

Hello,

I have discovered that this plugin had a significant impact on my website loading time. It represents around 50% of some page loading time.

I found out this by using the P3 profiler plugin.

I don’t really understand why there is so much impact. I would have expected the plugin to really have an impact only when a backup happens but not before that.

Do you have any idea on which function could eventually load so much the website?
