I have a system with 2 quad core CPUs running Xen on CentOS 5.1 64-bit. The kernel sees this system as having 8 CPUs. If I were to create 6 domUs, what would be the best way to allocate the CPUs to get best CPU and IO performance? Should all CPUs be allocated to all domU and let the system allocate as it sees fit or would the system perform better if each domU is restricted to fewer CPUs? Each domU is running a custom Java application that utilizes MySQL heavily. Application is heavily threaded. Thanks for any comment. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
