Any incoming 9SMBwriteX call on a non-signed SMB/CIFS connection greater than this value will not be processed in the normal way but will 10be passed to any underlying kernel recvfile or splice system call (if there is no such 11call Samba will emulate in user space). This allows zero-copy writes directly from network 12socket buffers into the filesystem buffer cache, if available. It may improve performance 13but user testing is recommended. If set to zero Samba processes SMBwriteX calls in the 14normal way. To enable POSIX large write support (SMB/CIFS writes up to 16Mb) this option must be 15nonzero. The maximum value is 128k. Values greater than 128k will be silently set to 128k.</para> 16<para>Note this option will have NO EFFECT if set on a SMB signed connection.</para> 17<para>The default is zero, which diables this option.</para> 18</description> 19 20<related>min receivefile size</related> 21<value type="default">0</value> 22</samba:parameter> 23
