Only in 2.2.21pre2aa1: 98_page-coloring-1 Only in 2.2.21pre2aa2: 98_page-coloring-13 Latest greatest updates for the page coloring feature. Recommended use for the number crunching is with shrink_cache=1 mode=1. Also selectable via boot option, read the code for details. Leads to improvements of 400% on alpha. Performance are completly reproducible after the feature is enabled. Works on x86 and on all other archs too. Mandatory feature for all the alpha clusters. Thanks for the collaboration in the developement of this patch to the Compaq department in Annecy and to Jason Papadopoulos for large part of the allocator engine. Andrea
