I tried to compute the initial size from the args object. It is hard because we don't know how arguments are used. For example, an argument may not be a number formatted as decimal, but the width of an argument. Another example: "%.3s" may be used to only read the 3 first characters of a very long string.
So I consider that it is *simpler and safer* to not guess anything from args, but only choose correctly the overallocation factor. I tried the following factors: 1 (no overallocation), 1.25, 1.5 and 2.0. It looks like 1.25 (pos*5/4) is the best compromise and offers the best performances. |
