Thanks for the quick response:

Essentially, This is what I would like to do:

Set up 5000 concurrent connections and vary the request rate from 5000 to
50000 requests per second.

Assuming I have setup 5000 easy handles and added it to multi interface, in
the first second, 5000 GET requests will be sent.
In the next second, using the same 5000 handles, I would like to send 10000
GET requests. This means 2 requests should be pipelined and sent in a
single handle.
In the third second, I would like to send 15000 which would have piplined 3
requests and so on.

If this possible is libcurl, how do I go about doing it?

Regards,
