1.2 跨境电商场景性能痛点
| 痛点类别 | 具体表现 | 业务影响 |
|---|---|---|
| 全球供应链复杂性 | 多仓库库存同步延迟、跨境物流时效多变 | 库存显示不准确，用户体验差 |
| 多语言多币种 | 12种语言、15种币种实时换算 | 计算复杂度高，渲染延迟 |
| 关税计算复杂 | 动态关税政策、个人物品免税额度、品类税率差异 | 计算耗时，影响下单转化 |
| 高清媒体资源 | 4K商品图片、短视频、360°展示 | 资源体积大，加载缓慢 |
| 跨境网络延迟 | API调用境外服务商、DNS解析慢 | 接口响应慢，超时率高 |
| 合规性要求 | 正品溯源、海关申报、税务合规展示 | 额外数据加载，页面复杂度高 |
| 移动端海淘用户 | 中老年用户居多、网络环境复杂 | 性能要求更高，容错率低 |
