The "Wizard Gap"

The Wizard Gap is an expression coined in the context of the Internet2's end-to-end performance initiative. It designates the difference between the performance that is "theoretically" possible on today's high-speed networks (in particular, research networks), and the performance that most users actually perceieve. The idea is that today, the "theoretical" performance can only be (approximately) obtained by "wizards" with superior knowledge and skills concerning system tuning. Good examples for "Wizard" communities are the participants in Internet2 Land-Speed Record or SC Bandwidth Challenge competitions.

The Internet2 end-to-end performance initiative strives to reduce the Wizard Gap by user education as well as improved instrumentation (see e.g. Web100) of networking stacks. The GN2 PERT focuses on assistance to users (case management), as well as user education through resources such as this knowledge base. Some commercial players are also contributing to closing the wizard gap, by improving "out-of-the-box" performance of hardware and software, so that their customers can benefit from faster networking.
