Hi,
I have a performance problem using postgresql when the connection is made
via ODBC with a windows machine using the latests ODBC drivers (Windows) and
PostgreSQL 7.3.3 (Linux).
The queries made by my Visual Basic program are very very simple. It queries
with as Select if a record exists and if so, it reduces stock with an Update.
For the benchmarks I do it 200 times.
If I test it against an Access database (located in a SMB server) it spends
3 seconds but against PostgreSQL 17 !! Exactly the same test programmed in C
(with pgsql libraries) and run within the same machine or another Linux
spends less than a second!!
So the problem seems to be whether with the ODBC drivers or with Windows
ODBC itself. Are there any parameters in the ODBC drivers that might help
reducing that big overhead added or do you have any suggestions to speed it
up?
Thanks in advance!
