How to perform load testing for website using JMeter

问题

I want to create a script in JMeter that simulates e.g. 100 users accessing our site over a period of 3-4 minutes.

We need to test whether our application can allow 25.000 users/day - that is 1.100 per hour.

For that i have made this Jmeter test:

and here is the result

and here is the graph

I want to know what this result is exactly telling us, if my test pass or fails, if yahoo.com (for which we have run this test for our example) can allow 25.000 users/day and if i am inputting my criteria / requirements correctly?

Thanks

1. I would advise to use better some custom samplers from jmeter-plugins instead:

Ultimate Thread Group: more flexible implementation of Thread Group allows to setup your load-testing scenario exactly how you want;
Response Times Over Time / Response Times vs Threads / Active Threads Over Time listeners: more demonstrative graphs as JMeter's default ones.

2. In addition to the @Qwe comment above: test not the single HTTP request but user's transactions: each test-thread should simulate a kind of real-user browsing activity: login (if any), navigating through the site, search, accessing/editing personal settings, logout, etc.
To emulate real-user add also "think-time" timer between transaction steps.

3. Control responses, at least the following:

response code of each user's request (@ Response Assertion);
duration - to verify non-functional requirements for critical transactions (@ Duration Assertion).

4. Look into corresponding JMeter documentation:
