JSI Tip 4156. Kernel Enhancements for Windows XP.

Registry

Larger registries, limited only by available system disk space. Improved algorithms for faster queries.

Support

Cross-session debugging, new quit and detach command for debugging without killing the application, and built-in user mode heap-leak detection.

I/O Subsystem

New input/output (I/O) interfaces for performance enhancement, while retaining compatibility with Windows 2000 drivers. Kernel-mode support routines for File System Filter driver improvements. Support for performance measurements in retail code, and improved low-memory performance.

Memory Management

Broad range of improvements, including logical prefetch to improve boot and logon performance, reduced paged pool usage, enhanced terminal server support, support of giant drivers, and Windows XP execution from ROM.

Power Management

Native support for processor performance control, including Intel SpeedStep Technology, AMD PowerNow!, and Transmeta LongRun for longer mobile computer battery life. Hibernate, standby, and resume performance have been greatly improved.

Improved Boot and Logon Performance

When a Windows XP system is first booted, data is saved about all logical disk read operations. On later boots, this information is used to pre-fetch these files in parallel with other boot operations.

Headless Support

For "lights-out" datacenter deployment and remote administration.

ccNUMA Support

Provides better performance for Cache Coherent–Non Uniform Memory Architecture (ccNUMA) computers, as well as an interface to let applications tailor their execution characteristics in the ccNUMA environment.
