Author: sir_richard Date: Sun Mar 4 17:56:00 2012 New Revision: 56000 URL: http://svn.reactos.org/svn/reactos?rev=56000&view=rev Log: [MEGAPERF]: This build introduces the following performance boosts: - Using a dead stack lookaside list for up to 5 dead kernel thread stacks. 1500% improvement when rapidly destroying/creating threads, such as during second stage setup and many winetests. - Using a free pool page lookaside list for up to 12 free non-paged or paged pool pages. 800% improvement when allocating big pages from the pool, as well as during pool expansion. - Using a bucketized per-processor and local list (in the KPRCB) for block sizes between 1 and 32 bytes. 1000% improvement when rapidly allocating/freeing small pool allocations, and 8x reduction in pool fragmentation.
