[Xen-users] throughput differences

["Daniel Thivierge" <Daniel_Thivierge@xxxxxxxxxxx>]

Hi all,

I notice a big throughput differences
between a normal user and root on Dom-0.  I did the command scp largefile
root@xxxxxxxxxxxxxx:~ and got the following result (test is a normal user):

From Dom-0 to Dom-1

Login root --> largefile 100% 4096MB
  8.5MB/s   08:01

Login test --> largefile 100% 4096MB
  2.9MB/s   23:46 <--???


From Dom-1 to Dom-0

Login root --> largefile 100% 4096MB
  8.1MB/s   08:27

Login test --> largefile 100% 4096MB
  8.5MB/s   08:02

I have a hard time figuring why will
root have faster throughput under Dom-0....  My setup is SuSE Pro
9.3 with Xen (default) for Dom-0 and Dom-1 has the Xen kernel but SLES-9
install for Dom-1.

Anyone did experience the same or can
someone shed some light on this?

Cheers.
