POC现场10秒左右会出现一次丢包 ** 当时流量情况参见[^POC-monit-stream.txt] ** 使用perf top -C cpuid查看CPU使用情况，tsg_conn_sketch消耗CPU较多 *** !image-2023-03-06-03-59-27-105.png! *** !image-2023-03-06-03-59-53-901.png!pengxuanzheng commented on 2023-03-07T20:44:48.234+0800:

udp_entry CPU占用率高的原因有2:

udp_entry 看到的pkttype是PKT_TYPE_TCPREORDER 状态，一直在加1 ** !image-2023-03-07-20-43-35-085.png!
tsg_conn_get_trans_layer_label函数占用率高

解决方案：

udp_entry 不再调用tsg_conn_update_translayer_label函数（本身udp 不用更新translayer label）
拆分 tsg_conn_get_trans_layer_label函数

更新后结果：

没有再丢包 ** !image-2023-03-07-20-50-52-064.png!
CPU占用率降低 ** !image-2023-03-07-20-51-45-548.png!
perf 结果 tsg_conn_sketch不再占用过高CPU ** !image-2023-03-07-20-53-03-633.png!

补充：[~luqiuwen]关闭重复流量处理插件

关闭connsketch插件的udp入口后，发现全部处理器的sys周期性增高，每次增高持续时间约1秒，大约10秒钟增高一次。怀疑和重复流量识别机制的bloom filter轮换机制有关。关闭sapp的重复流量识别功能，恢复正常，cpu利用率保持稳定（每个核心约50%），sys使用率较低（1%左右）。
