**Describe the bug (描述bug)** io-bound型服务，服务压力很低。查看工作线程数以及cpu使用程度都没有问题。bthread_worker_count:9，bthread_worker_usage维持在1.5以下。process_cpu_usage 0.5以下。排除锁的嫌疑。 使用rpcz发现耗时大的请求都卡在了最后Leave阶段，以下是其中一个，Leave core.HttpService.HotSearch阶段耗时350ms： 2023/01/18-14:58:29.320573 Received request(1378) from 127.0.0.1:53900 http log_id=0 trace=99c59dc851f7088b span=c51c916151762d93 14:58:29.320625 . 52 Processing the request in a new bthread 14:58:29.320672 . 47 Enter core.HttpService.HotSearch 14:58:29.320753 . 81 Requesting redis-server@xxx redis log_id=0 call_id=7142530642355 trace=99c59dc851f7088b span=[c51c916151762d94](http://xxx/rpcz?trace=99c59dc851f7088b&span=c51c916151762d94) 14:58:29.320770 . 17 Requested(49) [1] 14:58:29.322242 . 1472 Received response(14) of request[1] 14:58:29.322252 . 10 Processing the response in a new bthread 14:58:29.322256 . 4 Back to user's callsite ... 14:58:29.468671 . 17 Requested(467) [1] 14:58:29.469738 . 1067 Received response(5) of request[1] 14:58:29.469747 . 9 Processing the response in a new bthread 14:58:29.469751 . 4 Back to user's callsite 14:58:29.820964 .351213 Leave core.HttpService.HotSearch 14:58:29.821091 . 127 Responded(5280) **To Reproduce (复现方法)** **Expected behavior (期望行为)** **Versions (各种版本)** OS: CentOS Linux release 7.9.2009 Compiler: gcc8 brpc: 0.9.7 protobuf: 3.19 **Additional context/screenshots (更多上下文/截图)** -- This is an automated message from the Apache Git Service.
