'Opening' web pages , does require data to be loaded
if your pc is doing a 'virus scan' when first starting up
or 'auto scans' all web pages and downloads
then it will be forced to wait before it can open the page
the other possibly trouble with your internet connection (hardware or software)
impeding the data transfer
I can explain it to you.
But I Can Not understand it for you !
