Sorry…ignore that last post. Ran the wrong routine and posted the wrong time.

Here's the routine that I now ran:

for(int i = 0; i < 50; i++) {
int[] image = new int[8*320*480];
for(int j = 0; j < (8*320*480); j++) {
image[j] = j;
}
}

This took 34 seconds on my HTC Hero (v1.5 Cupcake).

FYI…I just ran this on my HTC Hero:

for(int i = 0; i < (8*320*480); i++) {
int[] image = new int[8*320*400];
for(int j = 0; j < (8*320*480); j++) {
image[j] = j;
}
}

Total time: 10.5 seconds

That would still be 5x the old iPhone. I wonder how this compares to the 3G or 3GS?
