890346 - On a FxOS devices, it takes a too long time to access the first screen

Status: RESOLVED WONTFIX

(Marketplace Graveyard :: Consumer Pages, defect)

Description

[Julien Wajsberg [:julienw]]

STR:
* connect on internet with your FxOS phone
* launch Marketplace
* Wait

Expected:
* the content should appear within a few seconds

Actual:
* the content appears in about 10 to 13 seconds -- and on a Wi-Fi
connection in France, which means this is probably worse in our target
countries.

This is way faster in Firefox that it is on my Unagi device, therefore there may be problems due to the low-entry device.

I attach the logs with timestamps so that you can see what's wrong.

One guess is that the big retrieved JSON is too big and takes forever to get parsed... and this is done on the main thread. Could be useful to split it ?

Not blocking leo for this. Marketplace team can fix out of cycle.

This is because we're not a true packaged app. We're two bugs (albeit big bugs) away from making that happen. Prototype packages load in under for seconds with a warm cache. 

Closing this as wontfix since this is tracked elsewhere. Check out the perf tag under the Marketplace component.
