Moin, I just did a quick comparison regarding speed of xen vs. vmware-workstation using a FAI installation test (FAI is a debian autoinstaller). Test setup: host "burns", athlon xp 2100+, 512MB, via chipset - provides an nfsroot (on hda) - second disk is partitioned into hdb1, hdb5, hdb6 - hdb5 and hdb6 are exported to vmware or xenU - installation pumps 4.1G of software from a local debian mirror to hdb6 (seen as hda6 in xenU/vmware ws) using apt and configures the software - assigned 192 M of Memory in both cases to the virtual machines - burns is connected to the local debian mirror using a 1000 mbit NIC and a switch xen setup: - xen 2.0.3, kernel 2.6.10, dma support enabled - the rest is an out-of-the-box-setup - support scripts are installed to move /lib/tls out of the way (BTW: wouldn't LD_ASSUME_KERNEL=2.4.10 have the same effect) - The installation took 7509 seconds vmware ws setup: - locally configured kernel 2.6.9, dma enabled - bridged networking - booting from a virtual floppy drive - accesses hdb{5,6} directly as hda{5,6} - /lib/tls is left in-place - The installation took 3068 seconds Why takes the installation within Xen 7500 sec and in vmware ws 3000 sec ? I expected Xen to be faster because of the lower overhead... What could cause this difference ? Could the scheduling be responsible ? -- c u henning ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
