Hi,
I had a test of comparing webservice performance with jbossws on jbos 4.0.4 and jboss.net over jboss 3.2.5
I found out that jbossws was working several times slower (!!!).

the results:
on JBoss 4.0.4CR2 on windows with document literal donotunwrap(wrap):
loop 10 times in 126632 ms
average round 12663 ms
loop 50 times in 456880 ms
average round 9137 ms

on JBoss 3.2.5 on windows with rpc literal:
loop 10 times in 23695 ms
average round 2369 ms
loop 50 times in 108643 ms
average round 2172 ms

here is the bean:

public class AmsItemManagerBean implements SessionBean{

 public AmsItem[] getAmsItemArray(boolean bool1, String str1, String str2, boolean bool2, boolean bo
ol3) throws RemoteException {
 AmsItem[] amsItems = new AmsItem[1000];

 short shrt = 1;
 long lng = 2;
 String str = "ejbTest";
 long begin = 0;
 long end = 0;
 long begin2 = 0;
 long end2 = 0;
 AmsItem[] utia;
 begin2 = System.currentTimeMillis();
 int rounds = 1000;
 for (int i=0; i<rounds; i++) {
 AmsItem amsItem = new AmsItem(str,lng,shrt,shrt,str,str,1,new Date(),shrt,new Date(),shrt,new Str
ing[5]);
 amsItems
 = amsItem;
 }
 end2 = System.currentTimeMillis();
 System.out.println("returning amsItem[] with length:" + amsItems.length + " in "+ (end2-begin2) + " ms");
 return amsItems;
 }
...
}

public class MainTest {

 public static void main(String[] args) {
 AmsAmsItemEjbService AmsAmsItemEjbService = new AmsAmsItemEjbService_Impl();
 try {
 AmsItemManager amsItemManager = AmsAmsItemEjbService.getAmsItemManagerPort();
 long begin = 0;
 long end = 0;
 long begin2 = 0;
 long end2 = 0;
 AmsItem[] utia = null;
 begin2 = System.currentTimeMillis();
 int rounds = 10;
 for (int i=0; i<rounds; i++) {
 begin = System.currentTimeMillis();
 utia = amsItemManager.getAmsItemArray(true,"aaa","b",false,false);
 end = System.currentTimeMillis();
 System.out.println("returned: " + utia.length + " in " + (end-begin) + " ms");
 }
 end2 = System.currentTimeMillis();
 System.out.println("loop " + rounds + " times in " + (end2-begin2) + " ms");
 System.out.println("average round " + (end2-begin2)/rounds + " ms");
 } catch (ServiceException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 } catch (RemoteException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 }
 }
}
