Dynamically linked shared libraries are an important aspect of GNU/Linux.

This article investigates the process of creating and using dynamic libraries, provides details on the various tools for exploring them, and explores how these libraries work under the hood.

Yes. The difference is typically about 5% for processor-bound tasks on x86_32. I doubt the effect is measurable at all on architectures like x86_64 which are not so ridiculously register-starved.
gcc will produce non position independent code if you tell it to.
