how do i use timers?

[Vijay]

Good day

 

I've a test plan with three http request with five users and need to run for
several iterations.

Test Plan

 Thread Group

   Http request 1

   Http request 2

   Http request 3

 

I need to run the same test for around 15 minutes with low delay time,
average delay time, high delay time and need to scale web server
performance.

 

I can use Constant throughput timer, but what should be the value given and
also what should be the value in Ramp up period.

 

Thanks

Vijay
