2007-12-30 Samuel Thibault <samuel.thibault@ens-lyon.org>
* linux/dev/glue/block.c (MAX_BUF): Set to sane stack-friendly 8
instead of blindly following VM_MAP_COPY_PAGE_LIST_MAX.
* vm/vm_map.h (VM_MAP_COPY_PAGE_LIST_MAX): Increase to 64.
* vm/vm_pageout.h (VM_PAGE_EXTERNAL_LIMIT): Increase to 2/3 free memory.
(VM_PAGE_EXTERNAL_TARGET): Increase to 1/2 free memory.
2007-08-20 Samuel Thibault <samuel.thibault@ens-lyon.org>
* vm/vm_object.c (vm_object_cached_max): Increase from 200 to 2000.
2005-05-11 Neal H. Walfield <neal@cs.uml.edu>
* kern/mach_param.h (THREAD_MAX, TASK_MAX, ACT_MAX,
ACTPOOL_MAX): Make them 64 times bigger.
* kern/zalloc.c (zone_map_size): Increase from 12 to 16 MiB.
