LOWELL, Mass. -- Virtual Iron Software (, a provider of enterprise-class software for server virtualization and virtual infrastructure management, today announced impressive results in the recent Intel vConsolidate benchmark performance tests with Intel VT FlexPriority - the latest extension in Intel Virtualization Technology (Intel VT). Intel ran its test with Virtual Iron’s latest release, Version 4.0 – which is among the very first server virtualization software solutions to support the new Intel capability. When leveraging Intel VT FlexPriority on Virtual Iron, virtual servers benefited from up to 40% faster boot time and up to 35% performance improvement on 32-bit Windows guests (Windows Server 2000 & 2003 SP1 versions).

Intel® VT FlexPriority optimizes and accelerates interrupt virtualization by improving virtual machine access to the Task Priority Register thereby enabling efficient Symmetric Multi-Processing (SMP) configurations of 32-bit guest operating systems. For users, this translates into more efficient performance in virtual environments for their critical enterprise applications.

"We are excited that Virtual Iron is taking full advantage of Intel’s latest performance advancements in our Quad-Core processors as well as the new extensions in Intel Virtualization Technology including Intel VT FlexPriority,” said Patrick Gelsinger, Senior Vice President and General Manager of Intel's Digital Enterprise Group. “The impressive virtualization performance delivered is the result of the productive strategic collaboration that Intel and Virtual Iron have established and our combined commitment to deliver solutions that address enterprise virtualization requirements."
