This Red Hat white paper describes the performance and scaling of an industry-standard Exchange application, Microsoft Load Generator (LoadGen), running in Microsoft Windows Server 2008 guests under Red Hat Enterprise Linux 5.4, using the KVM hypervisor. The host system was deployed on a Dell PowerEdge R71 0 G6 server equipped with 72 GB of RAM and comprising dual sockets each with a 2.53GHz Intel Xeon E5540 (Nehalem) processor with support for hyper-threading technology, totaling eight cores and 16 threads.
