Ncomp'ed code is SLOW

Question

Hi there,
we have a JSP which converts text to PDF
reading the text from a database CLOB. It
works fine but is slow.
We have the successfully ncomp'ed the code
but found the JSP being even 10% slower
then before. That is a surprise since we
actually expected a significant boost in
performance.
We are using Oarcle 8.1.7.1.0 with SUNS
"WorkShop Compilers 5.0 98/12/15 C 5.0"
compiler which I believe is certified.
We would be interested to hear if anyone
has got this ncomp code working and what
the performance is.
Anyone encountered the same problem ?
Thx.

This is an example of faster code to calculate the weekday.
It just take less that 1 seconds on my pc
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.GregorianCalendar;
public class Test {
        public static void main(String [] args) {
                try {
                        long a_day = 24L * 60 * 60 * 1000;
                        SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
                        long date1 = sdf.parse("01-10-1992").getTime();
                        long date2 = sdf.parse("19-03-2004").getTime();
                        GregorianCalendar gc = new GregorianCalendar();
                        gc.setTimeInMillis(date1);
                        int day = gc.get(gc.DAY_OF_WEEK);
                        int no_of_day = 0;
                        while (date1 <= date2)
                                if (day > 1 && day < 7)
                                        no_of_day ++;
                                if (++day > 7)
                                        day = 1;
                                date1 += a_day;
                        System.out.println("No of Weekday = " + no_of_day);
                catch (Exception ex)
                        System.out.println(ex);
}
