Module Name:    src

Modified Files:
        src/sys/kern: init_main.c

Log Message:
Bump default size of vnode cache to 1% of physical memory, instead of
0.5%, based on some quick measurements on a number of workstations and
small fileservers (including my home fileserver running simultaneous
builds of the NetBSD source tree and several NetBSD kernels).  This
brings the hit rate on my machines from below 70% to above 90%.  We
should be able to tune this as we run, by tracking the hit rate and
increasing the size of the cache if memory permits.

Some systems will still require significantly larger cache sizes.  Some
ports -- notably the 64-bit ones -- probably should use more than 1% of
physmem as the default due to the larger size of struct vnode.
