Subject Re: Very simple benchmark - are this typical numbers?

yes and no -- that's about 4200/s, which is typical for only a single
thread but 1/3 to 1/5 of what you'd expect it to max out (on our
quad-core test boxes) when you add client threads

however I didn't check) this took 40min (insert()ing one after another). Reading them one
by one in sequence delivers about 100/s, reading in 1.000er batches (i.e. multigetColumn())
takes 5-10s (depending on n, the higher the slower).
