Low perfromance in traefik v2.4.8 compare to traefik v1.7

Traefik Traefik v2 (latest)
1

my ingress does not have any annotations. Due to that I used the same ingress yaml file in traefik v2.
After traefik v2 migration HTTP request capacity is reduced 90%

The below one is my traefik V1 ingress yaml file. Based on that refer suggestion Ingress yaml for traefik v 2.4.8 version.
