Scaling Java Applications in a Red Hat Enterprise Virtualization Environment

This paper describes the performance and scaling of industry-standard Java applications 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 R710 G6 server equipped with 72 GB of RAM and comprising dual sockets each with a 2.66 GHz Intel Xeon X5550 (Nehalem) processor with support for hyper-threading technology, totaling 8 cores and 16 threads. The paper illustrates the low virtualization overhead of Red Hat virtualization on Java applications operating under virtualized Windows Server 2008.
