Hi,

I'm using Xen 2.0.3 with LVM2 as root for domain-0 and dom-U, and also another dom-U on gnbd. Kernel 2.6.10, custom config (kernel debug disabled), processor specific (Athlon). Benchmark use official Mysql binary (static .tar.gz from mysql.com) and sysbench (http://sysbench.sourceforge.net/) OLTP test.

On the same physical server :

Domain-0, LVM2, 128MB memory
OLTP test statistics:
   queries performed:

I understand the fact that GNBD is slower than LVM2, but is Dom-U supposed
to be that much slower compared to Dom-0?

Regards,

Fajar
