I am batch inserting insert statements into a database with fsync = on. My single disk system is on a 10k drive...even though I am inside a transaction there is at least 1 file sync per row insert.
Is this normal? On my hardware, which is pretty quick, I am limited to about 50 inserts/sec. If I operate outside of a transaction, the number is closer to 30. With fsync off, I can hit over 1000. IIRC in previous versions insert performance was a lot faster when in transaction, is that the case?
