Well I just checked what settings my NFS mount that works great is using. it uses:
Now I tried different rsize values with cifs as well, but that doesn't
seem to help (at least 64k made no improvement. Going down to 4k made
Looking at it carefully, it turns out trying to set it over 16k gets
ignored. Changing the option CIFSMaxBufSize on the cifs module to 130048,
does allow using rsize up to that value, and the speed goes up to 8.3MB/s
from 7.5MB/s. So it seems larger rsize makes it better. Given nfs uses
8 times larger yet and gets great speed may be a clue too.
