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?
