When you say slow, what are you comparing it to? So far, from our testing,
and from other responses, the new driver is much faster than the old one.
And there are of course, other reasons why things might be slow. Perhaps
the server was bogged down, etc.
How big were the 'text' fields? The new driver allows text fields to be 4k
big and handles it with a different API, whereas the old driver limited them
to 255 bytes. Maybe you might try a different data type, especially if the
data you are using is small.
If you want, you can send some more statistics on your table, such as the
fields and data types, and number of rows, etc.Byron
