I'm seeing a simple get taking a considerable amount of time.
a = session.query(Annotation).get(annotation.id)
This line can take anywhere between 0.15 secs to all the way up to 1.5
secs ... The query sqlalchemy produces is below. If I execute the
query in pgadmin, it consistently runs in 47
You have a tremendous amount of LEFT OUTER JOINS in there, and its hard to tell
but it seems like you're doing lots of with_polymorphic queries as well as
lazy='joined' styles of relationships, making for a very cumbersome query.
That it returns the first result quickly (that's your 47 msec)
