If set, generate the logs in a parallel process. Note: do not use it
on Windows and on systems with small memory foorprint.
<li>plotfork [&lt;&Delta;p&gt;]<br>
If set, run part of the processing (e.g. <a href="#SVG">SVG</a> plot
generation or <a href="#RSS">RSS</a> feeds) in parallel processes.
Actually, child processes are forked whose
priorities are the FHEM process' priority plus &Delta;p.
Higher values mean lower priority. e.g. use &Delta;p= 10 to renice the
child processes and provide more CPU power to the main FHEM process.
&Delta;p is optional and defaults to 0.<br>
Note: do not use it
on Windows and on systems with small memory footprint.
