Virtualization is already becoming ubiquitous in data centers for the consolidation of multiple workloads on a single platform. However, there are very few performance studies of server consolidation workloads in the literature. In this paper, our goal is to analyze the performance characteristics of a representative server consolidation workload. To address this goal, we have carried out extensive measurement and profiling experiments of a newly proposed consolidation workload (vConsolidate). vConsolidate consists of a compute intensive workload, a web server, a mail server and a database application running simultaneously on a single platform. We start by studying the performance slowdown of each workload due to consolidation on a contemporary multi-core dual-processor Intel platform. We then look at architectural characteristics such as CPI (cycles per instruction) and L2 MP (L2 misses per instruction) I …
