Two methods to get the same result, what's faster (Not creation, just access speed)?
(Pseudo code)
{
5 = object,
6 = object,
7 = object,
8 = object,
9 = object,
}
(Pseudo code)
{}, metatable:
{
__index = function(_, i)
if i >= 5 and <= 9 then
return object
end
end
}

The first is faster. It's a table index, rather than a table index, another table index (the metatable), and a function call.
Seeing as it's just 5 indexes, you can essentially ignore the memory difference.
You can just benchmark these kind of things yourself btw.

metatables in general are slower than any other way of doing a certain task. They only save memory, and not much unless you plan to have a lot of "instances" of an "object".
