We have migrated our codebase and servers as follows:
Originallly we had:
Crystal Reports 11.5 Release 2
Windows 2003 Server/32 bit
.Net 2.0 Framework
Visual Studio 2005
NOW we have
Crystal Reports 14 (Crystal 2011 Runtime verion 188.8.131.521)
Windows 2008 R2/64 bit
Net 4.0 Framework
Visual Studio 2012
What we are seeing is, our IIS worker process w3wp.exe when running Crystal Reports v. 14 runtime is using two to three times more memory than Crystal Reports v. 11. The amount of memory used appears to correlate directly to the number of pages when producing a .pdf.
This means to support our existing reports and user base we need servers with two to three times the available memory.
Is this a known issue? Are there any settings or code changes we can make to mitigate the issue?
