Multisocket multicores feature hardware islands - groups of cores that communicate fast among themselves and slower with other groups. With high speed networking becoming a commodity, clusters of hardware islands with fast networks are becoming a preferred platform for high end OLTP workloads. While behavior of OLTP on multisockets is well understood, multi-machine OLTP deployments have been studied only in the geo-distributed context where network is much slower. In this paper, we analyze the behavior of different OLTP designs when deployed on clusters of multisockets with fast networks. We demonstrate that choosing the optimal deployment configuration within a multisocket node can improve performance by 2 to 4 times. A slow network can decrease the throughput by 40% when communication cannot be overlapped with other processing, while having negligible impact when other overheads dominate. Finally, we identify opportunities for combining the best characteristics of scale-up and scale-out designs.
