Has anyone done a Capacity Planning study of SLK built on SharePoint Services? my customer is insterested in knowing how to determine the number of users based on a hardware scenario.
Please let me know if you had similar situation and share your experiences.

Hey there,

We have done some studies around this and based on some basic user scenarios (i.e. e-learning actions > assign to self > begin assignment) SLK does scale with additional hardware but puts quite a fair load on the front-end servers.

We saw one front-end web server and one SQL database support approx 100 concurrent users hitting the server hard (~400 req/sec). Adding another front-end (w/ load balancing) boosts the number of concurrent users to 350.

Keep in mind these are concurrent users repeatedly assigning content to themselves and launching/loading the content in the SCORM player. This is probably not a typical situation for anyone to have a user doing this but I think it simulates the heaviest possible useage on the site effectively.

what is the hardware that can be used in your study?

  • 2 web front-ends: HP DL385, 4x2.2Ghz, Dual Core, 8gb RAM, WinServ 2003 SP1 - load balanced using F5 BigIP
  • 2 sql back-ends: HP DL585, 4x2.4Ghz, Dual Core, 32GB RAM, WinServ 2003 SP1 - clustered

Hi, any other study on this matter? I receive another request from other customer and is asking me some sample of hardware configuration and number of users supported.
