I create report base on Telerik Reporting Q3 2015 SP1
my report contain 4 group headers
each data row return on report like detailsection|group1|group2|group3|group4
report use data return from database only fields that use format number digit or date format in expressions and no calculated field in report
report also use PageCount and PageNumber and 1 logo picture on PageHeaderSection
because this report have to be approved in the same document and data return from database is about 60,000 ~ 100,000 records, number of page about 3500-4000 pages
when I export as pdf it show message system out of memory exception in server side that report deploy in web MVC there is 2gb memory available.
my question is if export large data perform, how to calculate memory usage and plan to extend memory size on the server, or is there any way that improve my report when export file?
