I know there are too many parameters changing between the two servers
but I can't really change anything before tuesday. On tuesday, we will
be able to compare both servers with the same software.

Googlebot is indexing this site generating 2-3 mbits/s of traffic so
we use the googlebot to stress this server. There was a lot of clients
and a lot of queries.

Well, on high load, PostgreSQL scales well on the DP (load at 40,
queries slower but still performing well) and is awfully slow on the
MP box.
