                                If your score is under 2000, your server performance is bad. Scores from 2000 to 5500
                                mean
                                moderate performance. If score is above 5500 you do not need to do anything, server
                                performance
                                exceptional :)
                                <br><strong>Note</strong><br>
                                Changes in the system load can cause small differences in the score.
