[Xen-users] poor performance on nFORCE MB with Xen 3.0.2 linux-2.6.16-xen
Hi all, again i tryed Xen for normal home / development usage ... again i ran into a problem with it. There seems to be a problem with Xen 3.0.2 and nFORCE Motherboards. I used Xen 2 with nFORCE to and had a similar problem with performance earlyer and the List helped by telling to compile the Chipset Modules into the Kernel. I tryed this too on Xen 3.0.2 but with no sucess. The system boots a little bit slower than without a Xen Kernel, but it gets terrible on Disc IO within the running system. Creating an empty 100MB File timed as below, but after completing the command pdflush and kjournald consum 100% CPU and render the System for a short period of time (1-2 Minutes) useless. $ date ; time dd if=/dev/zero of=/tmp/test bs=1M count=100 ; date Wed Apr 26 06:56:38 CEST 2006 100+0 records in 100+0 records out real 0m17.097s user 0m0.010s sys 0m1.040s Wed Apr 26 06:56:55 CEST 2006 I''ve attached my ''.config'' for dom0 the modules not compiled into the kernel and loaded are $ lsmod Module Size Used by vfat 13248 0 fat 54812 1 vfat xt_physdev 2320 2 iptable_filter 2880 1 ip_tables 13144 1 iptable_filter x_tables 12868 2 xt_physdev,ip_tables dm_multipath 21128 0 video 16068 0 thermal 13384 0 processor 18544 1 thermal fan 4676 0 button 6672 0 battery 9476 0 ac 4868 0 will there be a better support for AMD and nFORCE ? on a Workstation in my Company the same Xen release works just fine, running on DELL and Intel :) Kind regards Michael Lang _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

AMD74XX is the chipset to enable if you want nForce support. -- Vincent Hanquez _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
