Good Morning Artur,

I am sorry for not responding sooner, I had some problems with my ISP
yesterday. The area that I have noticed which is slower is where I
filter on a dataset. Specifically this is where I am performing a
filter on my dataset. I do a containing search on a varchar(30)
field and it is very slow.

Comparing my converted application (this is a job costing / process
costing system so it has many records) back against the BDE
everything takes about the same time, except this search routine
which takes much longer (10 seconds instead of 2 seconds). Would the
fact that I have not noticed a performance gain running across the
network indicate that I have BDE settings interferring with IBO? If
so is there anything that people have encountered before that they
could identify as being redundant or negative in its effects on IBO.

Your thougts are most welcome.

Cheers


Aldus
