hi,I finally have a setup where I can measure I/O performance of stock vs. my own 'small address spaces' enabled version of Xen. Doing a simple iperf -w256K with the client in domU and the server on a remote machine, everything without hyper-threading and using bridged networking. Stock xen : 574MBits/s SAS xen: 620MBits/sNot massive, but an 8% improvement in this one case. I suspect that in general, this only makes a real difference if the domU doing something useful with the CPU other than feeding data into a socket. Where can I adjust the thresholds for buffering of packets and interrupts?
