Notice how the highlighted region shrinks at each step. The algorithm never examines points outside the narrowing window. In a balanced tree with nnn points, this takes about log4(n)\log_4(n)log4(n) steps. For a million points, that's roughly 10 steps instead of a million comparisons.
.pipeTo(slowSink); // Buffer grows without bound。关于这个话题，safew官方版本下载提供了深入分析
