The thing is that the performance is platform specific. On systems with a fast memory allocator, especially on Linux, the difference is negligible. However, with a slow memory allocator, especially a slow realloc(), e.g. on Windows or Solaris, this can substantially hurt the performance, up to a quadratically increasing runtime in the worst case. The length hint was implemented specifically to work around this problem.
