It runs quickly!!! But I don't know how to compare because looks like it retrieve fields by demand, when I put ctrl+end (go to the last record) it use a lot of CPU and disk, run quickly anyway. Correct me if am I wrong but, executing PgAdmin in the same server there aren't networks delays! And when the server is processing the query there isn't network traffic because is processing the result.

This isn't a dedicated database server, client application and server are running in the same machine!!! I have stop the client application too with same results.
Anyway I will do some network test to find a solution.
