Compuware Corp. (http://www.compuware.com), a technology performance company, has announced the top retail Web and mobile site performers for Cyber Monday based on the Compuware Performance Index. Apple was number two among websites.

Compuware’s analysis also found that, despite months of preparation by retailers, performance satisfaction for the top 50 retailers was down more than 12% on Cyber Monday from non-holiday baseline levels.

“The top Cyber Monday retail Web and mobile performers understand this simple equation: faster sites equal more sales,” says John Van Siclen, general manager of Compuware’s Application Performance Management (APM) Business Unit. “These retailers invested in the people, technology and best practices to deliver top Web and mobile performance on Cyber Monday, which is far more demanding than any other time of the year. Top performers made the most of this year’s increased online and mobile holiday traffic.”
