it lasts longer than two minutes, against 40 secondes with the local disk...

During startup, the iscsi is stopped for a moment and i can see "TCP Retransmission" with tcpdump(see below). After that, everything work fine...

The retransmission is harmless; it's the server retransmitting the response to the final iSCSI operation issued by iPXE (which is the write that Windows performs to flag an incomplete boot attempt).

You seem to have AoE also present in the mix, since there are AoE packets in your packet capture. Could you try simplifying the situation and using an image of Windows 7 which has not had the AoE drivers installed?
