Running this query:

INSERT INTO FACT_AGGR_IMP_1
SELECT TOP 110000 * FROM FACT_AGGR_IMP

on my server (compaq 8000 4 cpu 1 GB RAM) takes 29 seconds, running THE SAME query with 120.000 instead of 110.000 takes 3mins14secs, almost 7 times more!! Who is the guilty? Is there a way to understand the why of this sudden performance crackdown?

Thanks a lot, bye.
