Re: [Xen-devel] [BUNDLE] Testing a simpler inter-domain transport

It's unoptimized, but shows some promise. Here are the benchmarks for
tcpblast and tbench, on a uniproc 3GHz Pentium 4. I'd appreciate SMP
numbers if someone has hardware on hand:
UDP blast: tcpblast -u -s50000 dom0 9999
Current Xen = 254961 KB/s
Simple share = 233952 KB/s
TCP blast: tcpblast -t -s50000 dom0 9999
Current Xen = 86566.4 KB/s
Simple share = 135415 KB/s
Bidir tcp load: tbench 10
Current Xen = 31.9551 MB/sec
Simple share = 64.2113 MB/sec
I imagine the numbers for the Simple share should be pretty similiar for
domU to domU right? I also imagine that domU to domU under Current xen
should be considerably worse right?
Any idea why there's UDP degradation?
This stuff looks awesome :-)

It's not plumbed into xenbus, so creating LANs is a manual process,
using the dmesg output from the initial creation:
dom0# modprobe ohlan create
ohlan: created lan eth1 at address 0x1b6000
domU# modprobe ohlan address=0x1b6000
Feedback welcome!
Rusty.
