982143 - Swooop game much slower on Firefox OS than Fennec on comparable hardware

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Performance, defect, P2)

Description

[Kannan Vijayan [:djvj]]

Tested the Swooop game on Firefox OS master build (as of Friday, March 8) on a Nexus 4, and it was almost unusably slow, frame rates at around 10fps or so.

On Fennec on a nexus 5, the same game is playable and relatively smooth.  This should be looked into with urgency.  I was planning on doing it this week but I cannot due to a high fever.

Can we check what happens with this app on a Buri device on 1.4?

I locally confirmed that the problem seems to happen because of out of memory. "adb shell dmesg" log had the following log.

I am unable to find the swooop application on the latest v1.4 Buri build. I have also tried on the latest v1.4 engineering Buri build to no avail. 

Can a link to the application or the application itself be provided?

With the provided link I was unable to launch the application. The browser shortly crashes after launching the link on the latest v1.4 Buri build.

The application seems to uses a lot of memory. It might be impossible to run the application in buri/hamachi(256MB b2g phone).

Okay - can we test this on a Leo device then running 1.4?

Running the application on the latest v1.4 Leo build is extremely slow. The app runs at 5-10 FPS and is not usable as intended.

Okay - can we check the behavior on a Leo device on 1.3?

Out of 10 attempts with the provided link I was unable to launch the application. The browser will crash before the application can fully load for the latest v1.3 Leo build.

Seems like the behavior is better on 1.4, but still not great. So this isn't a regression.
