网络事件处理非常频繁，每帧处理的 channel 太多
map 成本异常高：4.12% std::_Rb_tree_increment
红黑树要优化：
O(logN)
cache 不友好
指针跳跃严重
内存分配/释放频繁：
1.36% cfree
1.74% TCPPacket::createPoolObject
2.05% string 操作
锁竞争
1.42% pthread_mutex_lock
内核网络路径吃 CPU，socket 操作非常频繁，网络中断压力
5.49% __fdget
3.82% handle_softirqs
优化优先级：
1.std::map
2.优化 Packet 分配
3.string要改，太多的fmt了
4.网络优化（优先级不高，可能等完全异步化了再做）
