| Before you do any tests suites, use CGP to determine that average number of webserver connections over a specific period of time (week, month, etc.). Then use that average as the number of concurrent connections, to simulate the benchmark under normal conditions. | Before you do any tests suites, use CGP to determine that average number of webserver connections over a specific period of time (week, month, etc.).

| - | Using Ragnar and this system load as an example, 4.7 is the average # of connections over one hour (3600 seconds). [[http://ragnarrelay.com/cgp/detail.php?p=apache&pi=localhost&t=apache_connections&h=ragnarrelay.com&s=3600|reference]] | ||

| Once you have the average number of connections, you can simulate the load under any length of time. Fifteen seconds (one quarter of a minute) is a good number that is both realistic in simulation as well as wait time for the tester. | Once you have the average number of connections, you can simulate the load under any length of time.
