We recently implemented Sharepoint 2013 in our domain. 16GB RAM, plenty of HDD space. Since last Monday it became slow suddenly. Because this is new only 25 people using it at the moment. I see 12GB of RAM is being used all the time. When we reboot it the memory usage goes down to 8GB and eventually goes up to 12GB.
On the resource monitor i see the processes below
Is this normal? do they have an effect on the performance?
