The performance of a web system configuration is inversely proportional to the average response time. In other words, the faster the web server software, database and scripts, the higher the performance.

In general, the following sequence of actions is recommended.

  1. Configure and optimize the server software so as to achieve maximum performance score.
  2. If despite all efforts an acceptable performance score cannot be reached, use more powerful hardware.
  3. For high load web projects, a performance score of 30 or better is strongly recommended. Perform measurements on a monthly basis and maintain the reached score by optimizing the scripts and database tables.

The performance is unacceptably low if the score of 15 or less; acceptable if the score is 15 to 30 and high for the score values of 30 or more.
