How to do a load test on a web service for 1 month ? and get response time, etc......

Hello :)

I was able to to load tests, however I don't quite well understand the relation between threads and Delay between tests.

Delay between tests, mean the delay between every teststep ?

Also, I have a service that I want to kill.....I ma using simple strategy but it not helping a lot.

I have my request that reads data from a txt file and send GET requests based on that value.

My file has almost 1300 records. I am using 100 Threads and ran the test for 14 hours with not luck :) I am trying to reproduce a scenario where this service dies after millions of requests.
