very low performance of Xen guests
...t the guests are extremely slow. For instance , in the most recent tests, a yum install kernel takes cca 1 min on the host and 12-15 (!!!) minutes in the guest, all time being spent in dracut regenerating the initramfs images. I've done rough tests with the storage? ( via dd if=/dev/zero of=a_test_file size bs=10M count=1000 ) and the speed was comparable between the hosts and the guests. The version of the kernel in use inside the guest also did not seem to make any difference . OTOH, sysbench ( https://github.com/akopytov/sysbench/ ) as well as p7zip benchmark report for the guests a speed...
