" Is anyone else still seeing network performance anomalies? I still cannot get over 500Mbps into xenU with any hardware that I have. This holds using kernels I build, or using kernel binaries from the 2.0.1 tarball. I tried tuning a e1000 driver, which greatly reduced the interrupt count, but had no effect on bandwidth. I can get 600 to 750 Mbps into domain-0 from a stock linux host. That rate then drops to around 500 after starting the etherbridge. Running top on Domain-0 claims the domain is over 60% idle. This is with e1000 and bcm5703 NICs on IBM x335, Dell 1650 and other platforms, and a variety of CPU clock speeds. Running iperf under stock linux 2.4.25 gets 940Mbps between any of them. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
