You have a connection which has an open/uncommitted transaction!!!
This means that every select is having to 'reconcile' all of the
accumulated record changes for each record in the database -- no wonder
you're running slow, you have over 3460,000 transactions of data to
'reconcile'.
Additionally, you are accessing a v1.x database (ODS 10.1) with v2.0.
Although supported, you would see the maximum benefit of the
optimizer/indexing changes if you backed up and restored the database
(to ODS 11).
