I was inserting a large number of records via insert statement (importing data from an Oracle DB)

While each sql statement execute in 50-55 ms, only one or two each second are processed, so totally useless for 100k rows.
Moreover, when pressing the stop button, app crashes, the DB is not modified.

Useful extra information
