Title: Slow startup time!
Post by: Mucip on March 08, 2020, 02:35:39 PM

Hi,
Everything perfect with LimeTeport except speed! :(

When I add #include<LimeReport> in the header of the form, it's dramaticly make slow the loading time. I'm waiting while formX.show()

Any advice  please?

Regards,
Mucip:)

Hi!
It's very strange. 
I have tested and I did not find any difference :)
If you just add the #include <LimeReport> nothing that can slow down your app is happen.
If you create an instance and start loading a report's pattern into it, a slowdown may occur in this case.

"If you create an instance and start loading a report's pattern into it, a slowdown may occur in this case."

I do like this. How can I do other than this way?

Hi!
Look, limereport can take some application's time for some reasons:
 - a report's pattern is big and contains a lot of items (limereport needs some time to parse it)
 - a report's pattern contains queries and limereport needs some time to run it (if queries are not optimized it can take a lot of time)

How to solve the problem:
 - load a report's pattern just before generation.
 - optimize query
 - use callback datasources

Hi,
As you advice, I loaded LimeReport when I press the "Print" button. Now it's better. Thanks.

Hi,
Please follow the Arin's advice. Load the report just before the generation.
If you load it when you create form then it's slow...
