Now it is peak time, and flow control disabled. Before it was 1% packetloss on small packets and 5-6% on large, now it is 0.3% on small, 1-2% on large. The flow-control required on this particular setup (probably linksys switches is too much crappy, no idea), and without it i experience "small" packetloss" But seems on this motherboard, by some reasons flow-control not working, maybe it is related to PBA. I will try to play with PBA now, but not sure i can do that. -- ------ Technical Manager Virtual ISP S.A.L. Lebanon
