Active Report very slow, specially on Ipad

[DanielZ86]

Hi everyone,

I am working on an active report at the moment and I am facing a problem that I cannot solve.

I have built a report and the MHTML file is not that big for an active report, 4.2 MB.
It has one main Deck and on each card on that deck are 3 lists, quite short around 4-6 rows and maybe 10 Columns. No charts or anything like that.
The list are created with data decks, the data deck is based on a querry which only includes the item for the data deck.

My Problem is, that the report reacts very slowly at the beginning when you push a button.
After the card of the deck was open a view times, it reacts faster.

When I do not format the list, it seems to run faster, but all I format is setting the width and hight of the rows and columns and some numberformatting.

Sadly it takes over 5 seconds before the card opens for the first time on an Ipad 2, by which I mean when it jumps from the homepage to the requested card.

Did anyone else experience something like that?
Can anyone help me?

Thanks in advance, Daniel
