This improved performance is the result of a rewritten threading
subsystem based on a 1:1 threading model, new kernel synchronization
primitives, kernel preemption, a rewritten scheduler implementation,
real-time scheduling extensions, processor sets, and dynamic CPU sets
for thread affinity. Almost all core kernel subsystems, like virtual
memory, memory allocators, file system frameworks for major file
systems, and others were audited and overhauled to make use of highly
concurrent algorithms.
