CACHE_POINTER_SHIFT indicates how many steps to downshift the |this| pointer.
|
||||
It should be small enough to not cause collisions between adjecent arrays, and
|
||||
large enough to make sure that all indexes are used. The size below is based
|
||||
on the size of the smallest possible element (currently 20[*] bytes) which is
|
||||
the smallest distance between two AttrArray. 20/(2^_5_) is 0.625.
|
||||
This means that two adjacent AttrArrays will overlap one in 2.7 times.
|
||||
However not all elements will have enough children to get cached. And any
|
||||
allocator that doesn't return addresses aligned to 64 bytes will ensure that
|
||||
any index will get used.
|
||||
|
||||
[*] sizeof(Element). Except is that really 20 bytes? Seems dubious!
