A request through traefik is much slower than through svc

Traefik Traefik v2
1

Requests/sec: 3795.83 // through traefik
Requests/sec: 31458.42 // through svc
It's an order of magnitude worse, how can I tune it？

What does nginx.yff.com resolve as? An internal ip address(RFC1918 range) or an external ip address ?

internal ip address。

[root@master01 test]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.9.68.231 master01
10.9.68.232 master02 ceph-admin
10.9.68.233 master03 mon01 stor01
10.9.68.234 node01 mon02 stor02 mgr01
10.9.68.235 node02 mon03 stor03
10.9.68.236 node03 stor04

[root@master01 test]# curl http://nginx.yff.com
