- Don't keep track of the page table reference count table in the address space structure, nobody was using this. - Instead of using either a global kernel pushlock for the kernel address space, and a per-process lock for process address space, always use a per-process lock (the kernel address space uses the idle process' lock). - Instead of acquiring/releasing the lock by dereferencing the process which owns the address space, hold a pointer to the lock directly. This removes an extra dereference, and also allows the kernel lock to work (because kernel address space doesn't have an associated process). - Inline the lock acquisition/release functions and the get-address-space functions. - Measured a 20% performance boost during boot-up, and 150% during installation. - Patch by Alex. svn path=/trunk/; revision=33092 |

======================== ReactOS Version 0.3.x Updated Dec 16, 2006 ======================== 1. What is ReactOS? ReactOS is an Open Source effort to develop a quality operating system that is compatible with Windows NT applications and drivers. The ReactOS project, although currently focused on Windows XP/2003 drivers compatibility, is always keeping an eye toward compatibility with older version of Windows NT family ( NT 4.0, 2000 (NT 5.0)) and new Windows NT releases (Vista, etc). Applications (Win32 API) compatibility focus is Windows XP. More information is available at http://www.reactos.org/. 2. Building ReactOS See the INSTALL file for more details. 3. More information See the media\doc subdirectory for some sparse notes. 4. Who is responsible See the CREDITS file.
