Subject: iperf receive data verify

Question/Comment:
Hi,

My name is Amit and I work in Performance Networking Lab at Intel Corporation. I've been using Iperf for my performance measurement tests for a couple of weeks and there's one feature that I would love to have.

- Is there an option to verify data that is received on Server side? This verification may not be very clever, just reading each byte and modifying a counter will be of great use. I wonder if such an option is already present or in your development pipeline?

- My second question is: How are multiple TCP connections on the server side handled? If I run 8 connections per port, I see only one iperf process running on the system. Is iperf not spawning multiple OS threads to receive data in parallel for all 8 connections?

Will appreciate your answers.

Thanks
Amit
