Subject Xalan 2.1.0 on JDK 1.2.2 runs better than JDK 1.3.1
Date Wed, 16 Oct 2002 08:00:53 GMT
Hi All,
    I run the cmd line examples on two diferents
versions of JDK always using the same vendor (SUN).
I got better performance on JDK 1.2.2 than JDK 1.3.1,
also i got the heap usage , using java
-Xrunhprof:heap=all.... and I saw that if you SUM the
colum "alive object" on JDK 1.3.1 is much bigger than
1.2.2 , my question are :

1) Why on 1.3.1 has worst performance ?
2) Why does JDK 1.3.1 use more heap space ?
3 What can we do to improve the performance on JDK
1.3.1 ?

Thanks in adavance !!!
