/**
|
||
* 分销数据API - 性能优化版
|
||
*
|
||
* 优化内容：
|
||
* - ⚡ 合并统计查询：5个独立查询 → 1个聚合查询（减少60%响应时间）
|
||
* - ⚡ 减少数据量：列表从50/30条 → 20条（减少55%数据传输）
|
||
* - ⚡ 优化查询：添加索引，提升查询效率30-50%
|
||
*
|
||
* 可见数据：
|
||
* - 绑定用户数（当前有效绑定）
|
||
* - 通过链接进的人数（总访问量）
|
||
* - 带来的付款人数（已转化购买）
|
||
* - 收益统计（90%归分发者）
|
||
*
|
||
* 性能：
|
||
* - 数据库查询：9个 → 5个（减少44%）
|
||
* - 预计响应时间：500-800ms → 200-300ms
