how to calculate time for execution of jrxml file?

[Kavita Kale]

Hi,

currently i m working on jasper reports,
i have used ireport 2.0.2 for creation of reports.
i m facing major performance issue for exection of reports in pdf, rtf ,xls & html format.also my one report jrxml contains 5-6 subreports & each having its own query to get that data.
that's why i want to calculate time to execute the jrxml file.

can any one help me how to do that ?

thanks,
kavita

Generally something can be timed like this:

long start = System.currentTimeMillis();
doTimeConsumingJob();
long stop = System.currentTimeMillis();
long secondsElapsed = (stop - start) / 1000;

You'll want to run the time-consuming job a few times before timing it, so that the JVM gets warmed up.
