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/s
Not 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?
Jacob
