Bug

Did you try using a 1.7.x configuration for the version 2.0?

• Yes
• No

What did you do?

• Run traefik ingress
• Expose some service without basic auth
• Expose the same service with basic auth and weak password encryption (e.g. bcrypt, complexity 5)
• Expose the same service with basic auth and strong password encryption (e.g. bcrypt, complexity 11)

What did you expect to see?

• roughly the same response time with/without basic auth

What did you see instead?

• response without basic auth: ~20ms
• response with basic auth (bcrypt 5): ~25ms
• response with basic auth (bcrypt 11): ~200ms
