Why iStatsPackAnalyzer

Web Based

iStatsPackAnalyzer is a web based tool. Yo don't have to install anything on your clients. Installing and upgrading are very easy.


Self Tuning Advice

You can write your own dynamic tuning advices.


Fast

  • iStatsPackAnalyzer sends compressed analysis results to HTTP/1.1 enabled browsers. Then, browsers de-compress reponse on the fly.
  • iStatsPackAnalyzer doesn't save STATSPACK files to server. STATSPACK files are processed in the memory-efficient data structures ON-THE-FLY while you post your STATSPACK files.
  • iStatsPackAnalyzer uses its own data structures such as Hash, Tree, List, etc. It doesn't use any database.
  • iStatsPackAnalyzer is a web based Java Servlet application. Java Servlet technology is faster than other technologies such as CGI.

Response Time Based
