Have 4 xen servers with windows domains. 2 work OK and 2 have xp domains with slow network performance. Doing most of the testing on a xen system that currently is not in production. Running xen 4.0 with 2.6.32 kernel from lenny backports. Have xp service pack3 freshly installed with no updates. Installed gplpv gplpv_XP_0.11.0.213.msi hdtack gives 60mb/sec which is good iperf gives ~15Mbits/sec Without gplpv is about hte same. A linux pv domu gives 686Mbits/sec Shows it as using Xen Net Device Driver. Things that I have tried that did not help: Disable Checksum Offload. Disable Large Send Offload. Disable Scatter/Gather. Adding /patchptr to boot.ini Any Ideas? John _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
