Subject Re: SQL with join are running slow

That sounds like the implementation of a HashJoin. You would want to 
make sure your smaller relation is serialized for this HashJoin, not the 
larger one.

Phoenix also supports a sort-merge join which may be more better 
performing when you read a large percentage of data for both relations.
