If I've read this section of code correctly, it seems to me that on most modern NFS servers (using TCP as the transport) the default and preferred blocksize negotiated with clients will almost always be 1MB - the maximum RPC payload. The nfsd_get_default_maxblksize() function seems obsolete for modern 64-bit servers with at least 4G of RAM as it'll always prefer this upper bound instead of any value calculated according to available RAM. For what it's worth (not sure if I specified this) I'm running kernel 2.6.32. Anyway, this file/function appears to set the default *max* blocksize. I haven't read all the related code yet, but does the preferred block size derive from this maximum too?
