Wait, that was possible? +1 key = 12x speed boost

A recent article on Habr explores a curious performance phenomenon when working with dictionaries (hash maps). The study reveals a counterintuitive result: adding the 102nd key reduces lookup time by 12 times compared to searching through 101 keys. The author analyzes the internal mechanisms of hash tables to understand what happens during this specific insertion. This article is useful for developers interested in algorithm optimization and low-level data structure memory management. The analysis helps clarify how hash table resizing or collisions can impact operational time complexity. The full breakdown is available in the original material, where the author explains step-by-step the reasons behind such a sharp performance jump.
