Yiyiyimu opened a new issue #3447: URL: https://github.com/apache/apisix/issues/3447
### Issue description In #3404, to test if chaos effect qps of apisix, I try to visit a route in the same frequency, calculate ingress bandwidth per second from prometheus metrics, and then compare before and after the chaos take effect. The current frequency is 1 time/s, which is pretty slow I think and the reason is that, when frequency is larger than 1 time/s, some visit would return `"503 Service Unavailable"` and the test would fail. The only plugin enabled is prometheus and no request limit related plugins are enabled, so I'm not sure the reason of this. ### Environment * apisix version (cmd: `apisix version`): v2.2 * OS: (cmd: `uname -a`) Ubuntu 18.04 * OpenResty / Nginx version: the one in v2.2-alpine docker * etcd version, if have: v3.4.13 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
