There's a tradeoff: a lower capacity means you can skip more space during queries (you zoom in faster), but the tree has more nodes and uses more memory. A higher capacity means fewer nodes but each node requires checking more points linearly. As a starting point, capacities between 4 and 16 are reasonable defaults, though the best value depends on your data distribution and query patterns.

冬在集市上买了10斤本地小米,比山西沁州黄好吃。话说回来,牌子也不白给,米吃不吃在其次,字儿记牢了——沁人心脾——“沁”字得民心。大米冬只认五常大米,好像吃个大米也要讲仁、义、礼、智、信。卖小米的老头儿兼卖腰带。小镇的集市就这种好,不像商场超市,分门别类固定搭配。小米、腰带,这两种东西一般不会做邻居。老头儿说一口标准普通话,这在遍地乡音的矿区不多见。他打开手机相册给冬看老照片:勋章合影、老兵合影、家庭合影……他说自己年轻时随部队支援过柬埔寨,战斗很激烈,能活着回来实属运气好。老人与冬聊得热络,聊饿了,指使冬去给他买张大饼。在集上卖东西的老人,有着共同的面目:倔强、寡言、木讷、大嗓门,穿戴款式老旧的衣帽和围巾,干什么都不慌不忙。多数情况下,冬专买这些老人种的和养的东西。冬认为他们很可能是最后一代用传统农耕劳作自给的人。他们的子女基本上都到城里去打工上学。
