QlikView Desktop - slow over Network

We use QlikView Desktop for our Apps (not server). We host the Apps on a LAN in London. The guys in the London office have quick response, we in Leeds have really slow responses. For example it takes them 6 seconds to open a 900Kb (that is kilobytes not megabytes) and it takes us 3 1/2 minutes. However if I reduce the number of sheets in the qvw from 20 down to 1 it reduces the time it takes to load dramatically even though the size remains more or less the same. It does not take 3 1/2 minutes to open other file types over the LAN. 

Also navigating through an Document opened from the LAN compared to one opened from my C drive is very slow. This is suggesting that the Document even once opened is constantly reading/writing to the Network. 

Does anyone know anything about what's going on? Yes I understand the Network is slow but why does it affect QlikView so badly? Why is QlikView so slow even after it is opened?

From a performance point of view is such fix path surely better as any expression/variable-stuff. But I suggest that you take a closer look on the above link about loading images into an application - maybe it's an improvement.

Thanks @marcus_sommer that would probably solve our issues that given the number of Applications we've got I'm going to hope the Network guys provide a fix to the underlying problem.
