ipa-ad-hoc 5 times slower than ipa-test

Hello,

I have successfully packaged my quite big app (3.5 MB swf and 24MB whole ipa file) in ipa-test package and it works quite good

But after compilation in ipa-ad-hoc package it is much slower - about 5 times, when loading and during work, especially when i.e. clicking an action for the first time (second time it is faster but not as fast as in ipa-test)

Is it possible? I've thought that these types of packages are the same - that this is compiled native code for iOS, and difference is only in certificates

I use 3.2 AIR, 4.6.0 Flex, Helo theme in compability mode for Flex 3 (unfortunately I cannot now switch to Spark components)

On android it works very ok (better even than in ipa-test mode), but I also would like have this app for iOS

Regards

Adam
