Did you change the build-id of Xen between the tests? Meaning did you check out a newer one between the releases? What is your underlaying disk for your guest? Did you flush the cache before you ran the tests? echo 3 > /proc/sys/vm/drop_caches Are you using stub-domain or normal QEMU? What is the xm entry for the disk in your .xm. Are you using GPLV/Novell VMDK/etc accelerated drivers under Windows? How many iterations of the disk I/O benchmark did you run? As in, are those screenshots of the first run, or the average over a couple of them. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
