Hello,

Can you give us some more informations regarding the way you link Access and Postgresql? Linked table? Pass-through query?
How do you query the table? With an Access filter?

In order to get the best performance, I suggest you put all the logic on the database, and use a pass-through query to query the postgresql view or function.

Objet : [ODBC] bad performance for Access, ODBC and Postgres

Hi,
I have very poor access whith a front end Access 2003, ODBC and Postgres 7.4.3.
Much time to find a record in a table ff 13000 records with indexs.
Sniffing the network, I can see a lot of traffic and the CPU of postmaster is about 30% (P4, 2.8 GHz). It seems that all the data's are backed on the client side and then, analyzed.
Does it exist an option to improve the performances ?
thanks,
