scaling

Hi,

I'm surprised about how long certain things are taking. Here's what
I'm doing:

1. create a temp_table which is 5-7 columns by 1e4 - 1e5 rows.
This part is pretty quick.

2. when its done, copy it into the big table which is 7 columns by
about 5e7 rows.

What I'm surprised about is that the 10,000 row copies take < 1
minute while the 50000 row copies take > 10 minutes.

I don't really know what information is relevant here, so tell me and
I'll provide any other details. (I'd describe the whole application
but didn't want to waste peoples time.)

Thanks,
