It takes too much time for the reports to load is what i experienced. I wrote 2 java files to develop a report. In the first report i designed the .jrxml file using iReport. All the fields were made in the design time. A db connection was made and a simple 'Select' query was executed. What i noticed is that the ' JasperCompileManager.compileReport(design); ' takes some time to compile. It took 5 seconds to compile. 2 secs to fill the report and 2 secs to view. So in all it took more than 9 secs for the report to appear on the screen. I feel 9 secs is too slow for a report as simple as this to generate. In the second report i took a blank .jrxml file without any fields. Using the jasperreports api i designed all the fields at run-time. I declared all parameters on runtime too. The query is also set at runtime. It took 13 secs to compile, 5 secs to fill and 2 secs to view. So in all 20 secs for the report to appear. 20 secs is too long. Is this normal. Is there any way to boost the performance ?? Even the slightest intention of help would be highly appreciated.
