Load Testing – Proof (Using Little’s Law)

There is a simple way to examine, whether the load test which we conducted is to a real extent or not.

 

The factors which we have to capture is

 

Hits per second,

Avg Response time,

Think Time

No of users simulated.

 

Thus substituting all the gathered data in the formula,

 

Total Number of users executed = (Response Time + Think Time) * Request per second

 

Note:

Thus while calulating using the formula, the result value should equal or should be greater than the total number of users executed.

 

From this deal we can able to find out, how much users the servers can handle. If the result value goes below the total numbers executed, then the servers are not capable to server these many users.

 

The Page size also can be verified using,

 

Page size = Throughput / Hits per second.
