I think what you really mean here is the function call / object
instantiation overhead, right?
Well, no. I'm interested in background information on hot run
time optimizers work now, i.e. whether they will optimize
for(i=0;i<n;i++) {
a.set(i,a.get(i).add(b));
}
into
for(i=0;i<n;i++) {
for(j=0;j<m;j++) {
a[i][j]+=b[j];
}
}
including optimizing array boundary checks away, doing loop
unrolling etc., and what the conditions are for these optimizations
to kick in. Sun Java 1.3 apparently had limited capabilities
in this area.
