Presto Rocks!

If you haven't tried Presto, you are missing out! Presto is a yum plugin that allows you to only download the bits you need using deltarpm. I just installed F11 on my wife's laptop and installed Evolution. Yum said 55M for download but with Presto-enabled repos it was only 1.5M or a savings of 98 percent! After the installation of F11 I ran yum update... 66M became 8.7M or a savings of 87 percent!

So if you have a slower Internet connection, and even if you don't, I'd recommend two plugins for Yum: yum-fastestmirror, which will locate the fastest mirror to you and get your packages from there, and yum-presto. Both of these plugins will make your experience much faster.
