[Xen-users] SMP enabled Dom0 or not?

[Stefan de Konink <skinkie@xxxxxxxxx>]

Hello,


I wonder if the performance of a Xen machine can be increased by 
disabling SMP in the Linux kernel by default, basically having one of 
the 8 processors tied to dom0.
In my scenario I use NFS or iSCSI as file backend. Looking at NFS there 
will be a lot of tapdrives, while in the iSCSI scenario there is fewer 
overhead in userspace processes.
Could anyone give me a hint on the performance increase or decrease 
using SMP vs Uniprocessor?

Stefan
