性能

库中实现了四种搜索方法,包括基于内存和基于文件的 BinarySearchBtreeSearch

从 benmark 可以看出效果最好的是 inMemoryBtreeSearch,所以默认的 search 方法使用这个。

测试结果如下:

$ node test/benmark.js

inMemoryBinarySearch x 70,936 ops/sec ±2.50% (81 runs sampled)
inMemoryBtreeSearch x 105,500 ops/sec ±21.11% (58 runs sampled)
binarySearchSync x 15,926 ops/sec ±8.47% (79 runs sampled)
btreeSearchSync x 42,713 ops/sec ±7.10% (74 runs sampled)
Fastest is inMemoryBtreeSearch

需要其他方法可以参考 test/index.js 调用。
