# Performance and Capacity planning

The Performance and Capacity planning data for Sharepoint 2007 RTM is now available. A nice table relating the requests per second to the number of WFE servers you need can be found at http://technet2.microsoft.com/Office/en-us/library/0a7b2b45-f633-46d2-a4fd-78691d4b8f631033.mspx#Starting

To calculate your requests per second RPS, you can use this folrmula

 Determining Peak Throughput Number of users = Percentage of active users per day = Number of common operations per active user per day = 32 Number of complex operations per active user per day = 8*3=24 Total number of operations per active user per day (common + complex) = 56 Number of business hours per day = 8 for e.g. Peak factor (usually ranges between 1-5) = 4 for e.g

Using the formula below, calculate the peak throughput (operations per second) required.

1.    # of users x & active users per day x # total operations per active user per day x peak factor

= ______

2.    Divide the result by 360,000 x # business hours per day = ______ requests per second*

NOTE: The constant 360,000 is derived from the following equation:

100 (percent conversion) x 60 (minutes per hour) x 60 (seconds per minute)
