I think they're just part of the system's regular disk cache, except for
the sysctl below.

Getattr, you mean? That just means that the client has stat()'ed a file
twice within the timeout specified by the vfs.nfs.access_cache_timeout
sysctl, and has pulled the value from its cache instead of querying the
server.

So here, 94% of the getattr calls were pulled from cache.

Dan,
Sorry, you were right I did mean getattr.
Just curious, does this mean that 94% of the NFS calls made, where
getattr() calls (175265837/185583924 = .944)?
Thanks,
Brian
