TPS Calculation

Hi,

We are in a processing of buying hardware load balancer. Each vendor is telling a different story i want to know how to calculate TPS and required Through put when buying a loadbalancer.

We will be hosting our intranet portal using this, we have around 10,000 users and are expecting 5000 concurrent session at a given time. The application is using sharepoint 2013.

Thanks

best to see MS definition which they refer to RPS and throughput
@ http://technet.microsoft.com/en-us/library/ff758647.aspx

RPS   Requests per second. The number of requests received by a farm or server in one second. This is a common measurement of server and farm load. The number of requests processed by a farm is greater than the number of page loads and end-user interactions....

Throughput   Throughput is defined as the number of concurrent requests that a server or server farm can process....

the reference architecture as planning norm stated in rps and user base size

(Number of users X Percentage of users who are active) ÷ Request rate
Example : (700 users X 10% concurrent users)  / 30 request rate per hour =  70/30 = 2 RPS ( approx)
