Hi, I post again... It seems my post didn't reach the list... I get really slow results with NEC AMD 64 3400+ It has Gigabit ethernet card (RTL-8169), but I only get ~10Mbps when I try to clone to computers linked with one RJ45 cable (no switch). I did the test with LZOP compression and image created in january 2006. Do you know why I get slower results than when I clone old computers on my network? thank you very much! -- Stephane.
