Slow performance

[oladunk65]

OS : 32 bit debian unstable distro Browser : Latest nightly holly build Shumway 0.7.907

I did try the Box2DFlashAS3 demo on a old computer. Excellent for the purpose of testing.

Firefox used around 80 to 85% of the cpu and 33% of memory Rest of the cpu was used by the xserver.

I would love to get rid of Adobe Flash but for the moment it is not possible. I am looking forward to any improvements.

As I just said in the other issue, we're aware of many issues. Shumway isn't ready for prime time, which is the reason why it's disabled by default, and can only be enabled through either a hidden preference, or through installing the extension.

In addition to the other old machine I gave the demo a try on an old laptop. Equipped with
Display controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller

Not the hottest one around, but for testing it is a good thing to have. The demo did run a bit better on that one.

I hope that shumway would succeed before Adobe flash stop working. Otherwise Firefox would be of no use and I am forced to use chrome.

@oladunk65 the issue is lacking the expected performance details. Please publish metrics in simular environment (e.g. without the inspector running) for Adobe Player (in chrome?) so we will know when this issue is not an issue anymore. Otherwise this issue will be closed as incomplete.

You may close the issue immediately or do what ever you like.

On monday I will be at my office, with a more powerful machine I will repeate what I done and post what I observe.

But I will give you one performance metric. The "arrow" on the page
http://mozilla.github.io/shumway is spinning nice with google-chrome (flash 11.9...) and firefox(11.2.202.310)

With shumway the spinning arrow goes around very slow. Less than half the speed compared to the adobe plugin.

From the webconsole I got the following output.

At my office I have an an Linux, Debian unstable distro 64bit, Dell Precision T3500, 12GB RAM, Quadro FX 3800, NVIDIA driver from www.nivida.com

"http://mozilla.github.io/shumway/main.swf" is running better compared to the old hardware at home. But the adobe flash plugin is faster.

Hmmm, I'm confused is Box2DFlashAS3 located at http://mozilla.github.io/shumway/main.swf ? Could you also define "faster" in terms of CPU usage or percent from normal rate?
