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.
