+*** Adaptive read buffering of subprocess output.
+
+On some systems, when emacs reads the output from a subprocess, the
+output data is read in very small blocks, potentially resulting in
+very poor performance.  This behaviour can be remedied to some extent
+by setting the new variable process-adaptive-read-buffering to a
+non-nil value (the default), as it will automatically delay reading
+from such processes, to allowing them to produce more output before
+emacs tries to read it.
