I have a .net4 winforms app with sharp map. It uses openstreetmaps tile layer.
It works great, but when I installed this app to another PC (Windows small business server 2011) I recognized a very interesting and annoying thing:
- by ADMINISTRATOR user openstreetmap is as FAST as on my developer machine, very delighted with it
- by another USER, who has also admin rights, openstreetmap gets EXTREMELY SLOW :(
It is half a minute to load a 800x600 map...
I checked internet connection speed from this user account by speedtest.net, it is fast enough (30MBit/sec) .
There are no any apps running that need heavy network traffic.
I also tested googlemaps and bingmaps in SharpMap, they are also very slow in this account in Sharpmap.
I also checked their behavior from Internet browsers, they worked great on all of them, at very high speed.
What could be the reason of this problem?
