.It Va kern.maxbcache
Limits the amount of KVM reserved for use by the
buffer cache, specified in bytes.
The default maximum is 200MB.
The default maximum is 200MB on i386,
and 400MB on amd64, sparc64, and sun4v.
This parameter is used to
prevent the buffer cache from eating too much
KVM in large-memory machine configurations.
