Poor performance when using backgrounds

Hi all, i'm getting a loss of performance just by using a background image... i'm doing like everybody else i think:
local bg = Bitmap.new(Texture.new("background.png"))
stage:addChild(bg)
If i don't set any background image, the performance of the game is fine... once i put an image (even low-res ones), the performance is clearly affected... any ideas of what may be wrong?
I can see this running the app using Gideros Player on the phone...
Thanks!

How do you measure the performance to see its decreasing?
And how much does it decrease?
I can run smoothly for example "Farm Tower", done with AndEngine. I use it too in my apps ("Cute Balance" for example, and it runs Ok) till now that i've found Gideros.
Ok, my device is not the best on earth
Do you think it can be the gideros player in the specific device? The player demands for a better device?
Thanks!
I remembered that @GregBug open sourced the game. If possible, can you test that game with the current version of Gideros?
Regards,
and Gidhelix is my first try to "code" with gideros so is not optimized... and is not well coded.
even my upcoming lib (collision system) in the examples/test files i use a background (320x400 tnt collision logo) but i can't notice differences if i put background or not.. (huawei 8650) ...
some time ago i tested a private beta of "super daddio 2" that use a "massive" background and paralax system and run smooth on my huawei device (it's the slower device that i have togheter with ipod 2^gen ... and i test everything on this devices...)
let me know how run Gidhelix...
i'm curious now...

@cvieira hmm.. it doesn't make sense at all. (maybe after changing landscape to portrait, only half of the background image is visible and OpenGL doesn't fill the region outside)
if for the authors is ok i can upload a video... (@ar2rsawseen ?)
may be a GFX HW limitation/BUG of your device ?

We are actually optimizing it right now to get more performance, but on the other hand adding more animations and small details to make it more polished, so in the end I don't think there would be a difference.
I remember reading from somewhere about splitting large image into small images leads to slight increased performance, or at least shorter loading time?
Mashballs run really fine on my U8650

@GregBug - Thanks for the testing!
I tend to now put all my images onto a packed texture (using Gideros Texture Packer) but I also tend to create a tilemap of my backgrounds and add this image to the texture to save image space and time due to less texture transfers. If all of your images will fit onto one packed texture then you only have to transfer 1 correctly sized texture to the GPU.

Maybe in a better device than mine this happens also (decreased performance - measured in FPS - in landscape with background image), but because it runs much faster user does not experience great difference...
Maybe someone can make that test so we can have no doubts... if you have any time available to do the test with some of your games, or a template one (such as soup ninja from @atilim or Gidhelix from @GregBUG), i will be appreciated!
Thanks!
