Quality and reliability improvements

CLR1

  • Fixed a floating-point overflow in the thread pool’s hill climbing algorithm.

  • When you observe high CPU usage by ntoskrnl!KiPageFault that originates from BGC (as indicated by the clr!*gc_heap::bgc_thread_function), you might want this change so that the GC no longer uses the OS-implemented GetWriteWatch function to track BGC heap modifications. That process is very expensive because each of these page faults must take a process-wide lock. This is especially noticeable in the recent versions of the OS. You are probably seeing that most of the CPU is spent in the ntoskrnl!ExpWaitForSpinLockExclusiveAndAcquire function. This fix makes GC use CLR’s own implementation of the GetWriteWatch function instead.
