Loading comments much slower than original Vue HackerNews

[yehosef]

If I open something with a reasonably large amount of comments
https://vue-hn.now.sh/item/15790687 (255 comments as of now)
vs
http://vuejs.github.io/vue-hackernews/#!/item/15790687

and the difference is huge. It takes me about 1.5-2 seconds to render all the comments on the V1 version and about 4.5 seconds on V2.

Is it possible to speed things up or is it a result of Vue2 or the vuex? (I hope not..)

Also the JS heap:
V1 goes up to 42MB , final at 33MB
V2 goes up to 140 MB and stays there

Hi. It happens because two reason which I found:

1. Recursive calling api when fetching comments. I have fixed it in PR
2. Loader hide and comments show when all comments will be fetched. If we want to see comments quickly we have to show comments earlier when first N comments will be fetched.
