BTW, but is the OS filesystem cache was introduced for this!?
I see that all unices around me (linux, solaris, sco) have very
intelligent fs cache, that can work far better than samba implementation.
For our site, I see disk access only when the first client accesses
the directory, subcequent accesses takes results from fs cache
(for all other clients also) -- there is no disk activity there.
If samba will have its own cache implementation, then on this system
this actually will _decrease_ performance, will require more additional
resources (notably RAM) and decrease stability.  I recall that kernel
know far more information about filesystem than samba can have, and
kernel knows also available RAM size that can be used for caches,
and it keeps cache only once while samba will keep it in each smbd
