Join in with filing excessive CPU bug in AIR

There is common knowledge that AIR apps can sometimes be CPU hogs. Well Grant Skinner has written a great blog post about how an AIR application in Flash that does nothing uses 4% of his new Mackbook pro CPU. It’s worth pointing out that Grant finds this only with Mac and not Windows and it is also seen in the Flash Player.

He is urging you to file this in the bug database at Adobe called Jira, the bug is numbered FP-2009 so do a quick search for that.

In the mean time Grant has created a workaround solution that effectively cuts the framerate of your movie when running in the background. The class (called framerateThrottler) is available here and read the full post over at GSkinner.com.

There is a response from the Adobe AIR team that includes some more performance tuning options available to developers.

Leave a response, or a trackback from your website.

A response to the whole AIR performance discussion has been posted by an AIR engineer.

The post has some more tips and tricks for enhancing performance when developing desktop apps with Adobe AIR. Framerate throttling seems to be a key element here, and those who are doing more application stuff can reduce this right down.

Read more tips over at the site.
