I like the plugins, but it seems I have to wait for 30

Hello,
I like the plugins, but it seems I have to wait for 30 minutes to an hour (or not at all) to actually get them to load when I'm in the backend of my wordpress site.

For instance: Defender won't even load the Dashboard. It did originally and I followed the steps to harden by site and then it just stopped loading. With Hummingbird, I have to reset it and then start all over each time I want to run a performance report. Is this normal? Or is this because of my hosting provider?

Thanks,
Caroline
