Hi all,
I’m trying to extract edges from the oracle table using the oetl tool, and at first the speed retained about 2000 records/sec for quite a long time, but suddently fall significantly to several hundred records/sec and retained that speed or even slower since that, just as the following pictures show:
So I’m wondering what factor suddenly made the ETL process slow down significantly, since the server only had this process running. And what can I do to improve this situation?
