@Kindar

The overall average CPU usage, when combining all the values and dividing by 12, equals ~89%.

Comparing the graphs to htop, it's not too far off, though ultimately, since the DigitalOcean graphs are not live graphs, I would trust what htop is showing.

That being said, for only 40 visitors, there's numerous Apache processes being spawned, which is going to chew through a lot of CPU and RAM. My initial guess would be that Apache is running its stock configuration or it's poorly optimized given the numerous processes being spawned.

Suggestions can be made, but they'd be just that, suggestions. If you really need such a large size Droplet due to traffic or other needs, then I'd honestly look in to hiring a sysadmin to help you with the optimization and configuration aspect.

I don't recommend that too often, though given the size, that'd be your best bet so you can work one on one with someone to look at what's going on and let you know what you do to reduce it without having to copy and paste suggestions back and forth.
