Why is sfml slowing down my computer tremendously?

I'm using sfml and when I run a simple application it uses tremendous amount of resources.

Is this because it has no limit to the amount of resources it takes and I need to give it a limit?

I just definitely notice it is taking up a great deal of resources.

I'm very new as I started using it yesterday.

maybe you're leaking memory somewhere. Can you post the code for the program you're running?

I doubt it... It's a simple program.
EDIT: I'm running this on a linux box btw.

This code is also something I made independently to be used in my pong game. Obviously just to see how the ball would/could work.

You're not limiting your frame rate anywhere, so it's going as fast as it can.
On my machine, this runs at more than 1500 fps (with 9% CPU usage).
