I have to say that it seems odd that MF3 may be more processor hungry than MF2, all the heavy duty stuff goes on inside the DL. The berry app works fine on my iPad 2 and 3 and it has far more going on than MF3 so it can be done. The A&H apps are also slick and effectively lag-less, even the iLive one which has double what the X32 has and four times the capability of the DL1608.
I mentioned the exact same thing pretty much on page 8 of this post. It's weird for sure, if the "other apps" have no issues on the older iPad 2 and 3. But MF 3.X seems to tax the resources, either the DL or the iPad or both. I have a slight feeling that we're all going around in circles, speculating on this. The only one(s) that can theoretically answer this is BenO and Mackie.
And it appears that even though they say they recognize there’s a problem and they are working on a fix in the next update of MF 3.X they are being quite silent on the reason for the issues. I’m sure this is either to cover their behinds or they don’t really and truly know why MF 3.X as they stated really requires a faster iPad CPU and more system memory to run as it should.
Too bad the hardware side of the DL806/1608 couldn’t benefit from a “Ready Boost” feature like Windows. Just plug in a reasonably large SD Card, say 16GB and voila, the DL now runs like lightning. Never going to happen though. Just wishful thinking on my part.
