Goal

Universal Event Loader (UEL) performance is very slow. It is also observed that during processing, UEL executes below query which takes too much time (above 30 seconds).

SELECT DISTINCT batch_t.poid_db, batch_t.poid_id0, batch_t.poid_type,
batch_t.poid_rev, batch_t.created_t, batch_t.mod_t,
batch_t.read_access, batch_t.write_access,
batch_t.account_obj_db, batch_t.account_obj_id0,
batch_t.account_obj_type, batch_t.account_obj_rev,
batch_t.descr, batch_t.end_t, batch_t.hostname, batch_t.pid,
batch_t.program_name, batch_t.start_t, batch_t.status
FROM batch_t, batch_gel_t
WHERE (batch_gel_t.input_file_name = :1 AND batch_t.poid_type = :2)
AND batch_t.poid_id0 = batch_gel_t.obj_id0
AND ((batch_t.poid_id0 >= :3 AND batch_t.poid_id0 < :4))


What causes UEL performance decrease ? How to improve UEL performance ?
