The site speed has increased considerably.
I just installed the WordPress plugin and left it alone for 1~2 days.

As a speed improvement feature, it is perfect, but if I had to make one improvement, it would be to be able to see the total CDN bandwidth for all sites on the Rabbitloader admin screen.

Currently, we can only see the numbers for each site, so it would be intuitive to know if we should change the plan or not if we could see how much bandwidth is being used in total with a single glance.

Overall, I would say this is a pretty good buy.
I highly recommend trying it out during the Lifetime campaign.
