Hello, I'm testing a new supermicro motherboard with a couple of AMD istanbul + AMD SR5690/SP5100 chipset and I've experienced very bad perfomance on domUs. The dom0 is based on 2.6.31 (jeremy tree) and the domU is a debian lenny. For example testing dom0 net with iperf I can see ~950 Mbit/s but testing the domU I can see only 197 kbits/s. Testing disk perfomance I've ~ 70MB/s on dom0 and ~22 MB/s on domU. Do you have any suggestion?
