84,000 spam to delete – help

I have installed this plugin on a site I am working on, and have over 84,000 spam comments to delete. I want to ensure that the site does not go down. Without making any adjustments, please confirm if I hit “Empty Spam” the batch process will start, that my site will remain functional, and that I will have the ability to keep working on it. thanks
