cache nfs file to local disk

[ProAce]

Hello,

There are the cachefs on Solaris and FS-Cache on RedHat can cache file
from nfs to local disk, does any similar software can be run on
FreeBSD?

In order to reduce the throughput and ops for nas server, I just want
to cache file from nfs to local disk. And the cache system can
controller the total size of cache file automatically ( the capacity
of nas is more more more large than local disk ).
