Can we get a more detailed breakdown of when the unacceptable lag is? is it after finishing the Persona sign-in process?

Retried just now and here's where the lag occurred for me:

* 4 seconds to load the persona login prompt
* 4 seconds after the prompt disappeared and the site content appeared

assigning to Sean.

Sean: I'm guessing we're dealing with the general speed of loading the dialog (which Francois is working on), and likely crypto performance. For this you'll need an actual device.

Chris: can you help get Sean a device?

Currently testing on a Galaxy S1, Firefox for Android.

I see about 4 seconds till the dialog is loaded. After signing in, it seems to take less than a second for the dialog to close and the Marketplace tab to start loading the "logged in" page. That would be when the crypto is taking place. However, it does take another 4ish seconds to load the next Marketplace page.

That load time seems consistent with the rest of the website I browse to (way faster than some, even).

Hm, I think we need a more detailed view of where the time is being spent. Perhaps profiling it could give you more data?

Sean - Are you able to still reproduce this with new trusted UI persona implementation?

I don't have a dev device, so I haven't tried.

QA wanted to retest eventually.

Tried this out today with the trusted UI implementation with persona - can't reproduce at all. If I end up catching this in more my extension testing coming soon with John, then I'll file a new bug. Closing this one as worksforme.
