933    On some systems, when Emacs reads the output from a subprocess, the
934    output data is read in very small blocks, potentially resulting in
935    very poor performance.  This behaviour can be remedied to some extent
936    by setting the variable @var{process-adaptive-read-buffering} to a
937    non-nil value (the default), as it will automatically delay reading
938    from such processes, thus allowing them to produce more output before
939    Emacs tries to read it.
