A VPS is basically a remote computer where you can perform different tasks. For e.g in your case, you can run massplanner on it.
It's really handy since you don't have to use your computer's resources and it's running 24/7, and the internet speed is spectacular(at least compared to mine)
A proxy is like the ip from your computer. It's helpful to avoid creating footprints for facebook, so if you use one account / proxy, and these ip adresses will be used only by you, then facebook won't know that all these accounts are yours, unless you create other footprints of course.
Which affect internet speed the least? VPN or proxies?Don't forget about VPN, they are like proxies but more expensive, but with a VPN there is some benefits (all your computers traffic is bottled up and sent via encryption to a location of your choice, and the location can be switched around easily) kinda like a anonymous proxy. But for FB purposes I don't have experience with VPN.
VPN will eat up like 5%-20% of your internet speed just because it goes on to do an extra step of making an encrypted tunnel between you and the new IP. But it is cool that your ISP and any "middlemen"/public-WIFIs actually can not tell what you are doing online. (but don't get all stupid and act like you are 100% anonymous, you are never 100% anonymous)Which affect internet speed the least? VPN or proxies?

Don't go paranoid with your proxy settings. Being too restrictive can be a fingerprint.
