[CS:GO] High var on server.

2 months ago when there was the old var type, my var was always below 1 and that was with 10 palyers 128tick. So i reinstalled the server after 2 months and now i get var with the new type 0,200-0,400. From what i can see is that ~0,030 is fine on 128tick. This was when only 2 players were on the server and no bots were deployed. But when i looked task manager it only used 2% of my cpu. I have i5 2500k @ 4,5Ghz witch should more than enough. Any suggestions? I tried setting high priority and messing with affinity but nothing worked.
