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 msecs. Any ideas? It seems to run longer if I issue the 'get' right after an update and another select query. If I wait a little bit (5 secs), then it seems to run closer to the 0.15 secs.
