You're apparently talking about an array of records (which obviously
contains pointers to the records), but the issue (I think) was the
records themselves, which store floats unboxed if they contain nothing
else.
I'm not sure that the data set in this case is large enough that giving
up abstraction and combining things into a single array would make a big
difference. It's also not what the Java program being compared to did.
