Compuware Announces Top Performers -- Why They Succeeded and
                         Others Struggled

DETROIT, Dec. 1, 2011 (GLOBE NEWSWIRE) -- Compuware Corporation
(Nasdaq:CPWR), the technology performance company, today announced the
top retail Web and mobile site performers for Cyber Monday based on the
Compuware Performance Index. Compuware's analysis also found that,
despite months of preparation by retailers, performance satisfaction
for the top 50 retailers was down more than 12 percent on Cyber Monday
from non-holiday baseline levels.

Compuware conducted an in-depth assessment of Web and mobile site
performance data for top U.S. online retailers using a combination of
Compuware Performance Index data, which measures performance using
Gomez Last Mile and dynaTrace technology to analyze transactions, to
determine why some retailers performed well and others did not.
Compuware revealed that the top Web and mobile site performers for
Cyber Monday included:


                     Top Mobile     
                      Sites: (out   
  Top Websites:       of 10         
   (out of 50         participants* 
   participants*)    *)             
                                    
  1. JC Penney                      
  2. Apple                          
  3. Symantec        1. Sears       
  4. Dell            2. Amazon      
  5. Abercrombie     3. Dell        
   and Fitch Co.                    
  6. Saks Fifth                     
   Avenue                           
  7. Macy's                         
  8. Best Buy                       
  9. L.L. Bean                      
  10. Overstock                     
                                    



"The top Cyber Monday retail Web and mobile performers understand this
simple equation: faster sites equal more sales," said 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."

Compuware's data clearly underscores that many e-commerce sites are
still not able to meet scalability demands that big days like Cyber
Monday present. Many retailers' websites failed to meet the performance
satisfaction demands of shoppers who expect web pages to download in
two seconds or less. Many retailers had web page load times of 10
seconds or more. Seconds of delay can mean millions of dollars in
potential revenue lost.

Based on deep forensic analysis of the top 50 eCommerce sites on Cyber
Monday using dynaTrace software, the top performers followed best
practices in order to maintain optimal performance:


  --  Light on third-party content;
  --  Pages not overloaded with hundreds of images or CSS files;
  --  Lightweight JavaScript; and
  --  Static images hosted on separate cache-domain served with Cache-Control
      Headers to speed up page load time for subsequent visits.




In contrast, many of the poorly performing sites had the following
issues impacting performance:


  --  Overloaded pages with too much content, which is cumbersome to serve;
  --  Heavy use of third-party plugins like ad services, social networks or
      user tracking;
  --  Too many single-resource domains (mainly due to third-party plugins)
      with high DNS and Connect Time;
  --  Heavy JavaScript executions in web pages (instead of pop-ups); and
  --  Multiple redirects bringing shoppers slowly to their final desired URL.




Compuware will publish a complete Web and mobile performance results
report for Black Friday through Cyber Monday, including the best
practices that retailers should follow to maximize performance for the
remainder of the holiday season. For a preview of the report's content,
