How can I perform an AB test with 1,000 concurrent visitors in just a second?

Say in 1 second, there are 1000 visitors on my site. And in another second there are 1800. In Another second again (3 seconds) there are already 3,000 visitors?

So the total visitors I have in just 3 seconds reaches up to 5,800.

I'm thinking about this command:

ab -k -c 1000 -n 1 http://mysite.com

Correct me if I'm wrong.

Thank you

You're wrong. You can't set c > n. 

ab -k -c 1000 -n 10 http://example.com/
ab: Cannot use concurrency level greater than total number of requests
