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)
