I want to install Puppy Linux on an old laptop that is otherwise useless. Will uninstalling Windows make it faster?

It’s an old Dell with 256.0 MB RAM and it’s been sitting around unused for a few years. I’m getting ready to install Linux, (I’m not really sure what I’m doing but I’m figuring it out. So far I’ve just been booting Linux from a disk, and it’s much faster than windows.) My question is this: if I get rid of Windows completely, will it make the computer faster, or will it not effect the speed when Linux is running? I really have no need for Windows on this machine…
