Problems with memory usage

[Daniel Schmitz]

Hi.

I'm using Stimulsoft Reports.Net for MVC 2014.2 and I'm having some problems with memory usage.
There are some cases where I need to render reports with around 5000 pages using business objects.
During the creation of the objects the memory stays near 700MB, but when I call StiMvcViewer.GetReportSnapshotResult, after around 1 minute the report is rendered, but my IIS proccess is consuming around 2GB of memory.

The problem is that it can happen of two or more reports beeing rendered at the same time, what would overload my server.

Searching the forum, I found some people having the same problem, and I found a solution that involved using cache like this:

Code: Select all

report.ReportCacheMode = StiReportCacheMode.On;
report.RenderedPages.CacheMode = true;
report.RenderedPages.CanUseCacheMode = true;

It almost worked. My IIS didn't consumed more than the 700MB it should. BUT, the rendering time increased from 1 minute to more than 3 minutes, so that is not a solution.

There are anything else I can try?
note: I also tryed to upgrade to version 2015.2, but there was no improvements.

Thanks in advance,
Daniel.

Hi.

I have tested in 2015.3 version, and there were no diference with cache disabled.
With cache enabled, it now use the same amount of memory that with no cache, and I cound'nt render my report (I canceled the render after 20 minutes...)

I'm attaching my View file (I changed the extension to submit the file, but the original one is .cshtml).

Thanks.

Hi Aleksey, I read all articles you suggested me, but none of them it's my case.
It's a simple report, with only one group band, and some text components.
The only detail, is that I have lots os cripts in beforerender events to calculate some values, and hide some fields depending on the parameters choose by the user.

Thanks
