hi,
I guess that db_links are set-up okay. have you scheduled the cron jobs when the other databases are less busy. what activity occurs on the 6 databases?

Hi

There are many factors that affect the data pulling. Shall these DBs are regularly monitored in terms of Analyze, Rebuilding Indexes etc. Most of the times the DB performance depends on the Query structures. Please check how they have built.
