Hello there,
I'm noticing a performance regression for what's matter the hard-disk I
pass to the domU (aquaria).
The slow-down is very noticeable even when moving small videos file
(~350mb).
In the configuration file of the domU, I pass the whole disk
('phy:/dev/sdb,xvdb,w') to the guest OS.
The distribution under both systems is Gentoo/Linux, x86 arch.
The hypervisor is always the same, in both scenarios (Linux xevelon
2.6.32-xen-r1 #1 SMP Sat Apr 10 13:37:02 CEST 2010 i686 Intel(R)
Atom(TM) CPU 330 @ 1.60GHz GenuineIntel GNU/Linux).
The machine is an Atom, so it's not capable of any VT technology but so
far it's a great machine and XEN is working just fine on it.
I attach you few logs I've gathered.
Thank you
