I recollect reading something few years ago, but not able to place my finger on the issue. IIRC it was something to do with the inserting session creating a HOT bloat because vaccum could not do anything on that live session. I will try to search for that post. But the symptoms were similar to yours. Initially good performance and then getting slower and slower.
Q: Is it straight insert or you do select or updates also along with insert.
