Since my import speed on my Dell Inspiron 8200 with 2GH, 2GB is around 3 h/s I install postgres 8.3 on an extern disc (USB2). Now I had recovered my old database and start importing:
The files to import are on the internal disc (this should speed up a bit). I have on the extern disc around 10-11 h/s with version 1.06.01m. And with version 1.06.01n2 the speed is around 14-15 h/s. So your last changes are in the right direction.
But I would like to use my internal disc in the future.
I will send you the traces.
