I have installed new SharePoint 2013 Farm on a single server (windows server 2012 R2) (VM, 8 processors, 12GB RAM)
I created one Web application defined it in DNS and it's working fine. A part of the fact that it's Very slow on the first load of the page.
It takes up to a minute. After when we switch between sub sites it's go very fast.
Do you have any Idea how can I resolve this problem ?
