Question:
The repeater in my application seems to be very slow in populating.
Is there anything I can do to improve its performance?
Answer:
Poor performance can be the result of a
wide number of interacting factors, so to
deliver a prescription with so little information
would be inaccurate.
That said, I can offer a couple of places to look
at for potential problems specifically
related to repeaters.
Make sure your RowFetchMode is set
to "Fetch As Needed" to avoid fetching all the rows that
may eventually end up in the repeater at
one time. Of course, if you need all the
rows for some type of aggregate total, you
will not have this option.
Second, if possible, reduce the number of
derived fields that use the SqlLookup()
method. Currently, OPO does an individual SQL
statement for each lookup, so having
three lookups could have some impact on the
performance of the repeater.
