Site appears to be running slower (esp. on Backend) after installation

Hello!

First off, I want to say I love your plugins ease of use. After having multiple issues with BackWpUp, yours seems to a much easier and effective solution.

Unfortunately, my site has had intermittent moments of slowness (particularly on the backend) ever since its installation.

Just wondering if there is a setting that might alleviate this (if it’s a known issue)? Would love to keep using this!

Thanks!
