    Windows Server 2016 Really slow on ESXI 6.5

    mars_cydonia Novice


      I have installed Windows Server 2016 on the latest version of ESXI 6.5.0b but it's almost unusable.

      The VM has 2 CPU and 2GB of RAM with VMware Tools 10.1.5 (5055683) and is used for Active Directory for my lab but it's really slow.

      For example for open DNS I take almost 10 secs.


      On ESXI I get High VM Memory Usage alarm but if I check on task manager on the guest vm ram usage is always around 40% and CPU is around 3 4% max and even if I put 4 gb the problem is still there.


      Is this a know problem or there's something that I can do to slove this problem beside downgrade to Windows Server 2012 R2?


      My Host ESXI specs are:


      Asus X99WS-IPMI


      128GB RAM DDR4

      1x SSD 250GB + 4xSSD 500GB on LSI 9260-4i on RAID 0

      ESXI Booted from USB Stick
