Client/Server Model broken by iperf3 implementation. worked in iperf

[GoogleCodeExporter]

What steps will reproduce the problem?
1. send traffic from two clients to a single server

What is the expected output? What do you see instead?

iperf3: error - the server is busy running a test. try again later

What version of the product are you using? 
iperf3  Feature worked in iperf

On what operating system?
Linux Centos

Please provide any additional information below.

We do not see this feature that was supported in iperf1 as "interfering with 
each other"

We are trying to test a 240 Gbps server with 36 Ethernet ports.
We need to have multiple client requests to achieve that speed.
A single client on a single port cannot do it.

Please add the feature back as a new optional parameter.
We need to simulate network servers like Apache which support multiple clients 
in a controlled manner.

This is the basic network design of the Client/Server Model.
How can you choose to violate the Client/Server Model in your "design"?

Please give us the option to support the Client/Server Model, if we choose to.

1. Iperf has moved to github  https://github.com/esnet/iperf .
2. As Bruce already explained  this is because of the design.
    https://code.google.com/p/iperf/issues/detail?id=140
3. You can use -P, --parallel  #         number of parallel client streams to 
run
