Yes, I know, the performace is/was bad. I found a major performace
bottleneck in the driver. I fixed it, try the attached ODBC driver.

How to:
* Backup your register
* Run the attached psqlodbc.reg
* Rename your current psqlodbc.dll
* Copy the attached psqlodbc.dll to the location of renamed psqlodbc.dll
* Run much faster!

Other tips:
* Start postmaster with fsync off
* Remove the index and recrate them later
* Turn off autocommit and/or begin transaction/commit

Hello there

I just made a test creating 2495 records from a C++ prog. into a postgres
table. This took me around 4 minutes. Doing the same against an access db
takes 30 seconds ! I use Version 6.50.00.00 from 04.02.2000.

What can I do to speed up the ODBC performance?

Thanks ... jr
