IPad Retina Mini storage stats sluggish..

Question

I've had my Retina Mini for a couple of weeks now and it runs just fine but every time I want to see how much space is left on the ipad (it's only a 16gb so space is tight!), it takes between 40 seconds and a minute to tell me I have X mb/gb left!
In case you're not sure how to get this info, it's in Settings, General, Usage. The applist appears on the top right eventually.
On my wife's ipad 3, running the same 7.04, it takes about 2 seconds. Both of us have a nearly identical app list installed!
I've tried reseting, restoring but it doesn't make a difference at all. Has anyone had this problem?

Hi maxgkx,
I understand you would like more information about storage capacity, and how it is reported. The following article provides helpful information on the topic:
How OS X and iOS report storage capacity - Apple Support
 Understanding storage capacity in iPad, iPhone, iPod
When you view the storage capacity of your iPod, iPhone, iPad, or other electronic devices within its operating system, the capacity is reported using the the binary system (base 2) of measurement. In binary, 1 GB is calculated as 1,073,741,824 bytes.
For example: The way decimal and binary numeral systems measure a GB is what causes a 32 GB storage device to appear as approximately 28 GB when detailed by its operating system, even though the storage device still has 32 billion bytes (not 28 billion bytes), as reported.
You can see this difference if you look at how your computer summarizes the capacity of your iPod, iPad, or iPhone’s storage when the device is connected to your computer. You will also see this difference in the About menu on your iPod, iPad, or iPhone. The important point to understand is that the available storage capacity is the same no matter which system (decimal or binary) is used. Nothing is missing.
The storage media in your Apple product, like all storage devices, uses some of its capacity for formatting, so actual capacity available for applications and files will be less. In addition, other factors, such as pre-installed systems or other software and media, will also use part of the available storage capacity.
