I have a problem with a X520-DA2 adapter in windows 7
When connected to a storage VIA Fiber or copper I get a transfer rate of 260-500 MB/s
But when the same card is connected to a Server 2008 R2 machine I get a transfer rate of 900-1110 Mb/s
Dose anyone know why windows 7 won't perform at full speed?
also when I configure jumbo package on 9014 the network seems to stop working
