Adjusting your TCP window size, tuning NIC parameters, configuring your network to support frames larger than the standard 1500 byte frame - these are all important when looking to configure ISCSI for performance. These techniques combined with the use of offload engines are sure to grant the implementor a successful deployment ISCSI offers great performance - but it requires much more tuning.

And this for every server. this point of view is mainly focused on $$, obviously very important.
