This is probably more like what you were expecting:
rows num values tuples(i.e array size) elapsed
1000000 1 106
1000000 10 14
1000000 100 13
1000000 1000 14
I didn't try to use PREPARE + EXECUTE here, just did "do" with the
INSERT + array size number of VALUES tuples (execute could well be
faster). The obvious difference here is we only do rows/(array size)
number of insert calls.
