+Using arbitrary objects as messages
+-----------------------------------
+
+In the preceding sections and examples, it has been assumed that the message
+passed when logging the event is a string. However, this is not the only
+possibility. You can pass an arbitrary object as a message, and its
+:meth:`__str__` method will be called when the logging system needs to convert
+it to a string representation. In fact, if you want to, you can avoid
+computing a string representation altogether - for example, the
+:class:`SocketHandler` emits an event by pickling it and sending it over the
+wire.
+
+Optimization
+------------
+
+Formatting of message arguments is deferred until it cannot be avoided.
+However, computing the arguments passed to the logging method can also be
+expensive, and you may want to avoid doing it if the logger will just throw
+away your event. To decide what to do, you can call the :meth:`isEnabledFor`
+method which takes a level argument and returns true if the event would be
+created by the Logger for that level of call. You can write code like this::
+
+    if logger.isEnabledFor(logging.DEBUG):
+        logger.debug("Message with %s, %s", expensive_func1(),
+                                            expensive_func2())
+
+so that if the logger's threshold is set above ``DEBUG``, the calls to
+:func:`expensive_func1` and :func:`expensive_func2` are never made.
+
+There are other optimizations which can be made for specific applications which
+need more precise control over what logging information is collected. Here's a
+list of things you can do to avoid processing during logging which you don't
+need:
+
++-----------------------------------------------+----------------------------------------+
