Code Runs SLOOOOOW in Xcode Sim, Fast in Corona Sim. Why?

Here’s a quick video that shows the problem:

Same code, but when I click the screen to spawn a little green guy, he falls in slow motion in the Xcode simulator but normal speed in the Corona simulator.

Nothing revealing (at least to me) shows up in the console log.

I’m not even sure where to look for an answer – any ideas?

PS - On the device itself (iPad) it hangs, which is how I discovered the problem in the Xcode simulator.

update to this :-

when build for xcode simulator the performance is good in iphone simulator but for retina and ipad simulator fps is maximum to 20
how ever this is not problem in actual device [import]uid: 35857 topic_id: 13165 reply_id: 48302[/import]

No problem on device?! Thank God! [import]uid: 24111 topic_id: 13165 reply_id: 72460[/import]

So if the device has no problem, but the Xcode simulator does, it sounds like an Apple performance bug and you should file a bug with Apple at https://bugreport.apple.com. In your bug report, it is also probably worth mentioning that the Corona Mac simulator also runs fine, though I suspect theirs is implemented very differently than ours so it may not be that significant to them.

You should include your built binaries with your bug report. They should be able to performance profile them.

I just did some tests of the sample programs in iOS Simulator (Iphone Retina) and don’t see any performance issues (build 703). Do you see performance problems with any of the Corona samples or just with your app?

Is this something that happened with the latest builds or has it been a problem with the previous release (591)?

Your posting implies this just broke in the latest release so we are trying to determine if this is a Corona problem or with the iOS simulator.

Update: I just realized that this is an old post. Are you still seeing the problem?

Tom, can you share your email adress with me so I can share a dropbox folder with you? [import]uid: 24111 topic_id: 13165 reply_id: 72487[/import]

Shared a dropbox folder now. [import]uid: 24111 topic_id: 13165 reply_id: 72509[/import]

Test this project: http://dl.dropbox.com/u/6498500/Chains.zip

The only thing that is changed from the build in samplecode is adding the gr_profiler and chaning the config file so that it says 60fps instead of nothing at all. Test building it for xCode and run it in the iPhone, iPhone(Retina) and iPad simulators. [import]uid: 24111 topic_id: 13165 reply_id: 72716[/import]
