I think there's a lot of missing info worth knowing:

1) checkpoints logs? Enable them, maybe the "slowness" happens
at checkpoints:

log_checkpoints=true

2) How many rows does each table contain?

3) HW: how many discs you have, and which controller you're using (and:
does it use a BBU?)

The more you tell the list, the better help you'll get...
