We are currently doing the tests, I'll post all result when we have finished.
We already found something strange, using an old computer (HP DC7900) running quite fast in production and a new one (HP 8300 Elite):
-1- Using one server - One gigabit switch - DC7900 client => Network usage 100Mbit/s
-2- Using one server - Direct connection (server to client) - DC7900 client => Network usage 800Mbit/s
-3- Using one server - Direct connection or gigabit switch - 8300Elite => Network usage 10Mbit/s
On "-3-" the link speed is 1 Gbit on bios, then negociated at 10Mbit during iPXE booting and staying at 10Mbit during transfer...

Playing with BIOS config on the new machine (HP 8300), we found that disabling AMT help a little: network link is now 1Gbit but transfer speed stay at 100Mbit...
