• Support for dynamic system address space, including on-demand allocation of system virtual address space and kernel page table pages, and support for very large registries.
• Support for non-uniform memory architecture (NUMA) systems and systems with large pages, including additional device driver and Win32 NUMA API's.
• I/O and section access improvements, including prefetch-style clustering for all types of page faults and system cache read-ahead (essentially pre-loading possibly-needed data into physical memory based on the current operation).
• General performance improvements, including translation buffer optimizations and improvements to internal data structures and algorithmic performance.
