JMeter: Run 300 concurrent requests per second

I have started 300 requests per second by providing following values: Number of Threads : 300 Tamp-up : 0 But I am getting following results:

summary +     55 in    21s 
summary +    225 in  31.1s 
summary =    280 in  31.1s

what different configurations would be needed to start all requests in one go?

IMHO, you have to take in account the time it takes to run the transaction itself.
I tend NOT to use synchronization, but to take measure on longer period of time, e.g. 15 minutes.

E.g., if your system is able to deliver one page in 2 seconds, you need to run AT LEAST 600 threads to deliver the throughput you want (probably more).
Also, remember that the time of a single page increase with the load, so a single measurement is not enough, AND take care of errors: you have to define an acceptable threshold for errors (e.g. 0.01%), and stop measurement when you go above that.

  1. If you need to start all 300 requests at the same moment you need to use Synchronizing Timer
  2. If you need provide constant load at 300 requests per second rate - you'll need Constant Throughput Timer

Two above would cover the majority of use cases, however if you want more control on your load pattern look into Throughput Shaping Timer (available through JMeter plugin)
