Looks like you are using 2 order N loops. why not use quicksort ? Tomcat
may have nothing to do with it.
Thanks

Please, can you put an example? I don't know how put the compareTo Method in my
servlet.

Collections.sort() them.
All you'll need to do is create a Class with all those fields implementing
Comparable, and implement the compareTo Method.
hope it helps

Hi,
I have a servlet and in this servlet I have a problem when sort an
array. If in Tomcat 5.5.4 (on windows) the order is very fast (about 2
seconds) , but in tomcat 5.5.9 is slower (about 25 seconds). I don't Know
why the same code has diferent time.
The code is the next. The array has 7000 elements.

calTiempoInicio.setTime(datTiempoInicio );
if (astrName.length > 1) {
//ordenacion de los arrays: astrName[intFilaArray]
int i, pasadas;

calTiempoInicio.getTimeInMillis()) / (1000) );
System.out.println("(ProcessFile) Time = " + intTiempoUtilizado );
