Use below Ant task to pre-compile your reports and then use ".jasper"
files within your project. This will concentrated that 70-90% of report
compilation time in compile process, and also do a pre-check of report
validation. Remember to place jasper  reports library in Ant's classpath
and use only fillReport (no compileReport needed).

<taskdef name="jrc"

<target name="jasper">
<mkdir dir="${tmp.dir}"/>
<jrc destdir="${classes.dir}" srcdir="${src.dir}" keepjava="true"
casesensitive="false" tempdir="${tmp.dir}"
<include name="**/*.jrxml"/>
<!-- under construction reports :) -->
<exclude name="**/NotYetReadyReport.jrxml"/>

formatting reports need graphýcal processing and it takes time, use crystal reports for same reports if it was faster then you can fine tune your jasper  report engine.
