> How does the performance profile work with SMP and the > interaction between domU and dom0 for CPU bound I/O? It's almost always best for dom0 to have just a single vCPU. > Are the CPU slices allocated independantly for each CPU in > SMP domains? Yes. The scheduler is fairly simplistic for SMP domains at present, but until we have a set of workloads to optimize against its not worth doing anything more fancy.
