[rules-users] Why would addPackageFromDrl() takes more time even for a small drl file with one rule

I have the following code to add a drl to the package.It takes 2-3 secs to load even a small drl file with one rule. Appreciate if anyone in the group throw some light on this. PackageBuilder builder = new PackageBuilder(); Date startTime = new Date(); SimpleDateFormat formatter = new SimpleDateFormat("H:mm:ss:SSS"); String datenewformat = formatter.format(startTime); System.out.println("Before Add Package from DRL-->" + datenewformat); builder.addPackageFromDrl( new InputStreamReader( getClass().getResourceAsStream( "/test.drl" ))); Date endTime = new Date(); SimpleDateFormat formatter1 = new SimpleDateFormat("H:mm:ss:SSS"); String datenewformat1 = formatter1.format(endTime); System.out.println("After Add Package from DRL-->" + datenewformat1);
