The OSS read-only cache feature was not introduced until 1.8. With 1.6 it will read the same data from disk each time. Note that if you have multiple OSS nodes it makes sense to stripe the file over all of the OSS nodes, since it is large and many clients access it, it will increase the aggregate bandwidth for access to that file.
