How many people can be online?

I'm wondering the speed of the computer is slowed when there are many people uploading image at the same time because a computer resizes an image use 100% cpu. I want to know how many people can be held at the same time?

Depends on how powerful the server is. There's no set number.

I suspect you're self-hosted then? Speaking of the server as "computer" usually indicates this. Please confirm.
