IIS 7.0 also provides a rich and reliable foundation for application development. First, Windows Server 2008 contains functionality that supports running the PHP scripting language on the operating system. Combine this with both kernel and user caching support, and developers have a flexible and powerful platform upon which to create all types of compelling and dynamic content.
The productive, agile new Web platform in Windows Server 2008 is boosted by the leading performance and flexibility of Intel Xeon processor–based servers to optimize the hosting environment for unique business requirements. Simply put, Windows Server 2008 runs more reliably, securely, and quickly on Quad-Core Intel Xeon processors.
With tremendous 64-bit performance and the broadest 32-bit application support, Intel Xeon processor–based servers offer fast Dedicated High-Speed Interconnects (DHSI) — point-to-point intersections between each of the four processors and the chipset. This increases throughput to support more requests, faster page loads, and timely application processing. For multi-threaded applications and heavy multi-tasking scenarios, Quad-Core Intel Xeon processors increase performance and threading headroom, allowing a greater number of simultaneous Web workloads. Functions are further enhanced by allowing systems to address extended memory with more than 4 GB of both

virtual and physical memory. For greater responsiveness to fluctuating Web workload demands, Intel Xeon processor– based servers provide up to 12 MB shared, on-die L2 cache with efficient L2 cache-to-processor data transfer. This keeps more needed data closer to the cores for faster access than off-chip memory, maximizes main memory- to-processor bandwidth, and reduces latency.
One very noteworthy benefit is the greater scalability — each Intel Xeon processor–based Web server readily adapts to fluctuating site capacity as well as to variable transactional volume. And Intel® I/O acceleration Technology (Intel® I/OAT) further enhances this benefit. Intel I/OAT improves proces- sor utilization and lowers latency to deliver twice the data movement, plus more reliable I/O. Together, these features support more requests and process network traffic faster.
Complementing these high-performance features is energy and cost efficiency. Intel Core microarchitecture increases responsiveness and productivity of multiple, simultaneous workload environments, while at the same time yielding better performance per-watt for ultra-dense deployments. The energy efficiency gained from the Intel Core microarchitecture helps enable highly dense 80-watt or 50-watt processor-based rack and blade form factors. This allows you to take back control of data center cooling, power limitations, and space constraints caused by server sprawl. Quad-Core Intel Xeon processor–based servers running Windows Server 2008 reduce overall space and electricity burdens in the data center, leading to lower energy and footprint costs.
Intel’s rapid cadence continues with 45nm Hi-K silicon technology. Available in Intel Xeon processor 5400∆ series, this next evolution in Intel Core microarchitecture includes an extensive array of improvements, including further energy efficiencies, increased transistor density, and
