Changed JS+CSS files to load async-ly. This forced me to update the structure of our Core.js a bit (the file which starts the app).

Thanks to pull request it loads faster although we have a regression because while the load, users cannot pan to landing page, the UI is frozen.

All libraries appended to DOM in a synchronous mode:

updated the code- can you take a look now?
it doesn't block panning now, but for some reason when you swipe back to landing page- there's no content on it.

any idea?

It takes way longer on a 2G mobile network; to the point it does not load.  Should I file a separate bug?

Comment 6

[Evyatar 'Tron' Amitay (everything.me)]

does it? it's weird, since nothing is downloaded while loading e.me, it's all local files. how could it take longer?

Comment 7

[Cristian Rodriguez (:crdlc)]

I don't have idea, I only load libraries :) I detected that sometimes there is a library where we wait for a long time due to sync storage. I don't have 2G connection to test it.

Comment 8

[Evyatar 'Tron' Amitay (everything.me)]

yeah we know the Storage is a major bottleneck in the loading time- but that's still taken locally... we don't go outside when we load e.me.

who can help us with this?

Naoki- are you sure that when you're on WiFi it works well, but on 2G it doesn't load? are we sure the network is the issue?

Unfortunately, I forgot my device with me to the office.  I'll record a video of it when I get back home.

It turns out that it must have been a bad mobile data connection.
Having said that upon first caching of the e.me page, it will take some time to load.  If it was already loaded before on wifi it comes up.

See video:http://www.youtube.com/watch?v=rSCxPLAXOS0&feature=youtube_gdata_player
you'll first see a cached e.me page, and then you will see the non-cached e.me page

OH

ok, we were talking about different things :) this bug is about how long it takes the actual e.me pane to load- when you swipe to the left.

you're talking about how long it takes results on e.me to load, if I understood the video correctly.

Comment 13

[Cristian Rodriguez (:crdlc)]

me too understood that ;)

Ah ok.  So swipe action versus loading is different.  I'll file a different bug then.  Thanks for the clarification.
