Re: the inefficiency of noncontiguous data - why?

I'm pretty sure there is no big difference in memory consumption.

The array itself takes up 16 bytes; that's 8 for the object, 4 for the
size, and 4 for alignment.
So your overhead is 16 bytes.
Add to that what the VM needs for memory allocation, which is also
insignificant compared to 64 MB.
