Changeset:   b3bf7915b59c
Branch:      None
User:        zzzeek
Date:        2015-01-05 00:05:31+00:00
Summary:     - scale back _Dispatch and _JoinedDispatcher to use a __getitem__ scheme
to start up listener collections; this pulls the overhead off of construction
and makes performance much like the descriptor version, while still allowing
slots.   Fix up some profiles.

Changeset:   18d3dc716390
Branch:      None
User:        zzzeek
Date:        2015-01-05 00:28:29+00:00
Summary:     - Structural memory use has been improved via much more significant use
of ``__slots__`` for many internal objects.  This optimization is
particularly geared towards the base memory size of large applications
that have lots of tables and columns, and greatly reduces memory
size for a variety of high-volume objects including event listening
internals, comparator objects and parts of the ORM attribute and
loader strategy system.
