I upgraded my system a few days ago and made the mistake of miscounting the number of PCI slots on my new board. after considering my options i choose to take out my 10g PCI network card since the server I'm connecting to has 4 1g ethernet ports on board. When I was using the 10G PCI card i was able to hit file transfer speeds of 600MB/s (using iSCSI and RAID5 in write-through) now however even tho the two system sit right next to each other connected via single crossover cable (cat6) I can't get a transfer speed any higher than 100MB/s I have confirmed on both systems that the NIC's are configured for 1G speed. are there any tweaks I can make to the advanced area of their properties that may improve that? it was my assumption that directly connecting the two systems and cutting a switch out of the picture would improve the speed but with or with-out a switch the speed remains unchanged, caps off at 102MB/s
