NO IT DOES NOT. Do you have no idea what root is for?
Here is a nice overview for you:
Getting root or rooting your phone is the process of modifying the operating system that shipped with your device to grant you complete control over it.
This means you can overcome limitations that the carriers and manufacturers put on your phone, extend system functionality, and even upgrade it to a custom flavor of Android.
The name root comes from the Linux operating system world, where the most privileged user on the system (otherwise known as Administrator on Windows) is called root.
Root DOES NOT speed up your phone, which you should have realised when you read the description of root. Root allows you flash a new ROM, which is a new GUI of your phone, or a new kernel, which MAY make your phone faster in certain aspects, especially if you overclock your phone.
By the way, I found the root description by simply typing into google "root for android explained" if you get confused again...
