Hi Martin,
The performance improvement from just #1 was dramatic - reading a 1M
feature shapefile went from over 1000 s to 32 s.
Wonder how complex your shapefile is.
It took me hours to create the following 65Mo shapefile, but it has been
loaded in 11 s only

Wow, your polygon should be really complex !
Will do some test and I'll report my results on this list.

PolygonHandler change:
((ArrayList) holesForShells.get(findIndex(shells,
minShell))).add(testHole);
/**
* Finds a object in a list. Should be much faster than indexof
*
* @param list
* @param o
* @return
*/
private static int findIndex(ArrayList list, Object o)
{
int n = list.size();
for (int i = 0; i< n; i++) {
if (list.get(i) == o)
return i;
}
return -1;
}
