Report performance

rbuser

Hi,

I have a report, whenever it's run, it started very fast generating the
pages, then it gradually starts to slow down, the last 10+ pages are as slow
as it can be. This is a simple report, no subreports, no images, just memo
and text, with 2 groups. I commented out all the events and it still does
the same thing. I have other reports that doesn't do this, they maintain the
same speed from beginning to end, unlike this one, starts out fast then
slows down. Any idea what could be causing it? I'm using RB 7.01 and Delphi
7 and IBX.

Thank you.

Have not heard of this before.

As a test you can try setting Report.OutlineSettings.Enabled to False. On
very long reports, the additional overhead of producing the outline can
cause slower performance.

As another test, you could try a data traversal test (without RB). Write
some code that loops thru the dataset and time it.

I notice you are using RB 7.01, you should at a minimum update to RB 7.04
which was the last produced release for RB 7.x. Email
info@digital-metaphors.com with your serial number and registration
information and request an update.

The latest release is RB 10.02 and it includes support for D6, D7, D2005,
and D2006. Delphi 2006 includes a new memory manager that results in faster
performance for all applications.

I noticed that you sai D2006 has a better memory manager, would RB 10.x help
D7 to have better memory management and better performance too? We are not
updgrading to D2006 any time soon.

It's a feature of Delphi 2006.

Thank you.

I tried turning off the outline but it still does the same thing.

I just got the 7.04 version and we will try it out.
