CVS commit: src/sys/kern

[Daniel Carosone <dan%netbsd.org@localhost>]

Module Name:    src
Committed By:   dan
Date:           Tue Jan 27 11:35:23 UTC 2004

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

Log Message:
Reduce the default BUFCACHE to 10% for now.  Too many users are
tripping over this getting too large, and suffering other performance
problems due to the lack of good backpressure shrinking the bufcache
when other memory is required.  Again, this tunable should be
revisited when the backpressure mechanism has been improved.

sysctl vm.bufcache can be used to manually tune those rare machines
that might need more than this.

See comments in rev 1.106 for more detail.
