Based on some tests we ran, it seems the biggest performance
hit you get from running within domU is from disk I/O. We
did some mysql read and write tests, and for both, our
performance is about half that compared to native. Has that
been others' experience?
Is there any way to make this better? We are using physical partitions. In contrast, cpu/memory tests appear to be near native. Does buying commercial Xen (XenSource) help in anyway? Do they have optimized disk drivers? johnn _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
