Hello,

We need some additional time for check the issue.

Thank you.

.... and now after 8 months are you asking for testing data for analysis? Or, Is your answer only result of the "checking the issue"

... seriously now. I am not able to send you it, because it is case of calculation of huge amounts of customers data.
Now our customer has problem in case of report, which has 200.000 data rows and it is counting some summary values placed in few groups. Using of your Totals functions means, that rendering of this report takes 20 minutes. And customer compares the speed with old reporting system, where the same report with the same data takes 4 minutes... that is problem for us to justify the reasons why we choose Stimulsoft reports, if you understand.

And I have to say, that the speed is problem of all your agregation functions. Please, check it. We have made some tests and it is possible to make calculation even three times faster. Thank you

Hello,

We made some improvements in that direction, and now we need the sample report which reproduce the issue for analysis.
We couldn't reproduce this bug on our test data.

Thank you.
