hi, I'm a newbee with jasper report and ireport. I have a problem when i run a subreport inside master report. Each subreport take too many time, may be 200ms. For exemple : I have a master report with 8 subreport (one subreport = one sql query) and one subreport = 200ms All subreports inside a band detail, runtime 200*8=1600ms, it' enormous! I need help for optimization (SQL ok) Thinks.
