将btcd的addrindex用户实际业务中的通过地址查询交易列

先公布下结果，基本不可行，除非你的用户量少的可怜

测试环境:

• os: centos 7

• cpu: 16 核 Intel(R) Xeon(R) Platinum 8163 CPU @ 2.50GHz

• memory: 65G

先上一下跑分结果:

测试方法如下:

1. 在bitcoin core区块链上随机选择2000个地址(存在交易记录)；

2. 在压测中，保证每次请求的地址不一样，这是为了防止leveldb cache的命中

3. 此次测试返回的交易列表的请求如下:

   • 得到交易的数量列表:{50, 50, 2, 16, 41, 50, 2, 50, 50, 50, 2, 2, 41, 50, 50, 50, 50, 2, 2, 2, 11, 2, 2, 24, 2, 2, 11, 50, 50, 2, 50, 2, 50, 50, 50, 50, 50, 2, 2, 2, 2, 50, 19, 2, 2, 19, 2, 50, 50, 50, 2, 2, 50, 5, 50, 25, 4, 2, 2, 2, 15, 5, 2, 38, 50, 50, 2, 50, 26, 38, 50, 2, 50, 2, 8, 2, 2, 4, 50, 2, 50, 2, 2, 2, 18, 8, 50, 2, 50, 50, 50, 2, 50, 6, 4, 50, 20, 6, 2, 15}

   • 总共得到交易的总数量: 2353

   • 平均每次返回的结果数量: 23
