1170111 - [ServiceWorkers] Check virtual list and model caching

Status: RESOLVED FIXED

(Firefox OS Graveyard :: Gaia, defect)

Description

[Francisco Jordano [:arcturus] [:francisco]]

We need to explore how the new virtual list:

https://github.com/etiennesegonzac/dom-scheduler

Can use a pregenerated model vial cached content in the service worker (old way of using render cache)

POC with the virtual list and caching via sw:

https://github.com/arcturus/dom-scheduler/tree/contacts-sw-cache

The way we use the render cache here is that we create a /model.json file that contains the first chunk to be render and the number of contacts.
That's the information that the list needs to do a quick first paint.

Will try another approach that is to save the information in the own index.html

Interesting results ahead:

- First paint packaged ~ 960 ms
- First paint with SW ~ 1100 ms (The SW serving is increasing the time)
- First paint with SW and Cache ~ 1000 ms (We save a bit but not much)

Will need to explore if the code added to cache, or the need of an extra request is what is not making us have a huge gain in the performance.

Closing this as fixed, since several tests have been done.

https://github.com/arcturus/dom-scheduler/tree/contacts-test
https://github.com/arcturus/dom-scheduler/tree/contacts-sw-cache

We need to check now the performance for SW and raw cache.
