Question regarding the rendering of subreports

[tpontow]

Hello Andrew,

I installed the new 2014.2 edition of Stimulsoft Ultimate (Dll version 2014.2.2000.0) and so i came back to my subreport rendering performance problem. I measured the duration of report rendering with and without subreport. I put all together into a VS2013 project including mrt report files. I also attach below an excel sheet with durations.

I listed the number of data records and the duration with and without subreports and there is an exponentially increase of elapsed time for the rendering process with subreport.

Is it planned on side of Stimulsoft to improve the rendering beaviour when subreports are involved?

Hello,

We made some improvements in that direction.
The patch will be available in the next prerelease build.

Now your report with 20000 records are rendered 5-7 times faster.

Thank you.

Thank you.

Hello Ivan,

i've installed now the latest prerelease build (Dll versions 2014.3.4.0) but i cannot see any improvement in subreport rendering performance. The elapsed times are nearly the same as before. Does the latest build really contain the changes you made for subreport rendering performance improvement? Or do i have to change something in code or report design so that the changes can take effect?

At that time i don't know where the problem is! (I know that sometimes it is between the screen and office chair )

Thanks

Hello.

We have checked your project with our 2014.2 and 2014.3.4 builds.
We have next results with 10000 records:

Code: Select all

                    2014.2     2014.3.4
without subreport      3.4s       3.4s
with subreport        64.8s       8.9s

Thank you.

Hello Aleksey,

i found out at last that my project used the wrong (= old) Dlls from the Global Assembly Cache. I now forced the project to use the 2014.3.4 Dlls and the rendering is much faster. So the duration times are similar to your table.

Thanks
