We also saw performance improvements going to the mainline kernel (2.6.24.*) from the CentOS 5 kernels. Don't forget to make sure you're not disabling ACPI on Barcelona by booting with noacpi, if you do then the kernel won't learn that it's a NUMA box as the old K8 table hack doesn't work on K10h and you'll get much worse memory bandwidth. cheers, Chris -- Christopher Samuel - (03) 9925 4751 - Systems Manager The Victorian Partnership for Advanced Computing P.O.
