Modified files:
sys/vm swap_pager.c swap_pager.h vm_kern.c
vm_map.c vm_pageout.c vm_pager.c
vm_swap.c vnode_pager.c
Log:
Significantly improve the efficiency of the swap pager, which appears to
have declined due to code-rot over time. The swap pager rundown code
has been clean-up, and unneeded wakeups removed. Lots of splbio's
are changed to splvm's. Also, set the dynamic tunables for the
pageout daemon to be more sane for larger systems (thereby decreasing
the daemon overheadla.)
