### Current Behavior # 1.开启限速插件，限速为每秒2万。 [root@ansible-wy ~]# curl -X PATCH -H 'X-API-KEY: blapp9f034335f136f87ad84b625c8f1' http://192.168.200.187:8080/apisix/admin/routes/test-admin-svc-ab -d

2、用ab工具测试，2w个请求，耗时2.5s，失败率接近90% [root@ansible-wy ~]# ab -n 20000 -c 100 -H HOST:testadmservice.st.testidc.com http://192.168.200.187/testAdmin/Env/ping.htm This is ApacheBench, Version 2.3 <$Revision:

blapp9f034335f136f87ad84b625c8f1' http://192.168.200.187:8080/apisix/admin/routes/test-admin-svc-ab -d '{"plugins":{"limit-req":{"rate":20000,"burst":0,"rejected_code":505,"key_type":"var","key":"remote_addr","rejected_msg":"limit by blqqd!","allow_degradation":false,"nodelay":false}}}' 2、ab压测，失败率高 3、取消限流 4、ab压测，无失败 ### Environment - APISIX version (run `apisix version`): 2.15.0 - Operating system (run `uname -a`): Linux VM87 3.10.0-1160.71.1.el7.x86_64 #1 SMP Tue Jun 28 15:37:28 UTC 2022 x86_64
