The automotive industry spends millions of dollars each year racing cars because it helps build better cars for regular people like you and me. If an auto manufacturer can build a V-8 engine with four valves per cylinder, take it to the race track and have a successful season, the same manufacturer can use that knowledge and experience to build an in-line four-cylinder engine that’s powerful, reliable and relatively inexpensive for consumers.
In the IT world, however, speed is everything. People don’t buy slow servers, and they don’t want their websites to load more slowly than the rest. So in this regard, IT is much like auto racing. You build faster servers and faster networks because it allows you to provide better service to your customers.
