There are arm64 cell phones; I suspect the workload on a cellphone is different enough from a server workload that it should be tested as well. The end results may indicate 64k pages are a win everywhere or they may indicate a need for two arm64 flavours when we eventually target higher-end phones. Sorry, I can't recommend any benchmarks that would simulate the cellphone workload. Thanks
