<samba:parameter name="read size"

<listitem>
<para>The option <parameter moreinfo="none">read size</parameter>
affects the overlap of disk reads/writes with network reads/writes.
If the amount of data being transferred in several of the SMB
commands (currently SMBwrite, SMBwriteX and SMBreadbraw) is larger
than this value then the server begins writing the data before it
has received the whole packet from the network, or in the case of
SMBreadbraw, it begins writing to the network before all the data
has been read from disk.</para>
<para>This overlapping works best when the speeds of disk and
network access are similar, having very little effect when the
speed of one is much greater than the other.</para>
<para>The default value is 16384, but very little experimentation
has been done yet to determine the optimal value, and it is likely
that the best value will vary greatly between systems anyway.
A value over 65536 is pointless and will cause you to allocate
memory unnecessarily.</para>
<para>Default: <command moreinfo="none">read size = 16384</command></para>
<para>Example: <command moreinfo="none">read size = 8192</command></para>
