BUG REPORT

I have a website that I'm trying to run through minikube and while everything works, loading a single page on my host browser take upwards of 2 minutes. Connections between Pods seem to be normal.

The problem might originate from VirtualBox, but I'm not sure. Here's the minikube config:

I did change the NIC to use the paravirtualized network but speed stayed the same.

I also tried #1353 but it didn't fix it for me. Here's a poorly representative screenshot of what's going on when I load the page and look at the network tab in Chrome:

screen shot 2017-04-12 at 09 05 46

minikube version: v0.18.0

Environment:

What you expected to happen: Get the page load under 600ms would be acceptable.

How to reproduce it (as minimally and precisely as possible):

Start minikube with VirtualBox and run a rails server and try to access it from the host. That page needs to have external asset to increase the number of connection going through minikube.

Anything else do we need to know:

My setup might not be similar to what others do and while unlikely, it could be the cause of all my problems. Here's a gist of my Dockerfile and k8s config file

Notice how the image is "empty" and only loads the Gemfile and then when the image gets loaded into the pod, a volume from the host is mounted on that image. That allows me to develop on my host in the same folder as all my other project while running everything through minikube.

Let me know if you need extra information, I'd be glad to help!

I'm going to go ahead and freeze this issue so it doesn't keep getting closed. That said, this is an issue with 9p itself and can't really be worked around unless we end up replacing it.
