You can choose on the processor. Unless you are building for a 8 or 16-bit CPU, this isn't worth messing with. -``BOTAN_VECTOR_OVER_ALLOCATE``: The memory container ``SecureVector`` -will over-allocate requests by this amount (in elements). In several -areas of the library, we grow a vector fairly often. By -over-allocating by a small amount, we don't have to do allocations as -often (which is good, because the allocators can be quite slow). If -you *really* want to reduce memory usage, set it to 0.
