Registration of new routes very slow

[JorritPosthuma]

Describe the bug
We have a platform where we dynamically add new routes. In version 0.40.2 is takes around 2 second for a simple container to be accessible through the route, but in 0.50.0-rc5, it takes around 20 seconds

To Reproduce
The route we apply is as follows:

apiVersion: ambassador/v1
kind:  Mapping
name:  module_x_mapping
prefix: /module_x/
service: module_x
timeout_ms: 0

We create the service with this config using the Kubernetes TypeScript SDK.

Expected behavior
A clear and concise description of what you expected to happen.

Versions (please complete the following information):

• Ambassador: 0.50.0-rc5
• Kubernetes environment: Docker for Mac 2.0.0.2 - Kubernetes: v1.10.11

Additional context
Looking at the Ambassador Diagnostic Overview, the route get's picked up very quickly. But then it still needs 20 seconds to become reachable.

This should be fixed by #1153.

[kflynn]

Fixed in RC6.

[JorritPosthuma]

Actually, I tried it, and it still takes 46 seconds to become available.

In 0.50.0 GA? How many services do you have?

(Also, the Slack channel might be a great choice for more interactive discussion here.)

[JorritPosthuma]

Ah, ok, no, I tried RC6 :). Will try GA first! If that doesn't resolve anything then I'll contact on slack.

PS: Around 10 services

[kflynn]

Ahhhhh that makes much more sense. RC6 definitely had an issue there, but 0.50.0 GA should be much better for you. 😄
