hi,

i have made few simple tests
2 supermicro P4 HT 3Ghz 2GB ram, 2x sata in sw raid1, net tg3 driver
OS centos4.4 (dom0,domU)

server1 has xen 3.0.1 (2.6.12.6 - compiled, SMP on) server2 has xen 3.0.3 (2.6.16.29 - compiled, SMP on)
domU paravirtual, 128MB ram, loopback

server1
domU-1-1#wget http://ip-domU-1-2/test.file (150MB)
throughput 17-20MB/s (average 18MB/s)

server2
domU-2-1#wget http://ip-domU-2-2/test.file (150MB) (-O test.file or -O /dev/null gave same results)
throughput 1-8MB/s (average 4.5Mb/s)

can you explain someone bad results for xen3.0.3?
