Inserting per se should be a constant-time operation, independent of the
size of the table. The index updates are not constant-time, but I can't
see any reason for their performance to suddenly fall off a cliff
either. What I'm wondering about is triggers --- in particular, do you
have any foreign keys in this table? Checking the foreign references
could be where the problem is.
