The maxBufferSize value is the minimum of snd_buf_size / rcv_buf_size
and the MaxBufferSize field returned by the server in the
SMB_COM_NEGOTIATE response. So if you cannot get it to go higher, it's
because the server has set the limit.

Note that there's a "large read / write" mode and a patch in the
patches directory for enabling it. It's very old so don't bother
trying to apply it with the 'patch' command. You'll have to manually
modify the JCIFS source yourself to get it to work. Also I'm not
convinced it will actually improve performance for most people. But
depending on how important throughput is to you you might check it
out.
