hello

I Installed a website with dotnet nuke. but i have a big problem with loading time of this website. when i open this website in any computer for first time it take about 1 minute to load with 256kb/sec internet speed. but when i continue to visit other pages, it would be very fast. i tried to change the caching  configuration , but never changed in any configuration.

i think all of the files and images load together when i open the website .

the website address is:
