I installed MSDE (mssql limited version) and copied the same data from pg to MSDE, I was surprised cuz running the same query with the same data and MSDE seems to be a little bit faster, after the changes in postgresql.conf described in the previus message pg perfomance increased a little but still there is no big difference against MSDE, considering hardware, pg is in a real server (dual Xeon 2.4 Ghz, 2G RAM, 3 36G SCSI drives on a RAID5) and the server is not in production, MSDE is in a AMD athlon 1Gh with 256RAM y should expect better performace from pg. I wonder if ODBC could be affect performance so high, my current ODBC driver is 7.03.02. Thanks -- Josué Maldonado.
