how to send 10000 http request for every 20 seconds using JMETER

Question

What should be the ramp up time when i need to send 10k request[each request has 6http subsequent calls], I need to send 1 request per minute. and i need to send one request for every 20seconds

Answer 1

Your post contains 4 questions which are mutually exclusive so I provide a generic answer:

1. If you want to send X requests at exactly the same moment:

   • Add X thread (virtual users) to Thread Group
   • Add Synchronizing Timer to the request and set Number of Simultaneous Users to Group by to X
2. If you want to send 1 request per minute - add Constant Throughput Timer to your request and set Target Throughput to 1
3. If you want to send 1 request each 20 seconds - the same approach as for point 2 but Target Throughput will be 3

Ramp-up is the time period for starting virtual users, normally normal people use it for gradual load increase, for example if you have 10 users and 10 seconds ramp-up JMeter will start 1 user each second, if you have 10 users and 20 seconds ramp-up JMeter will start each user each 2 seconds, etc.
