    ESXi 6.5.0 Slow Disk Performance

    dobrasekwifi Lurker

      Hi, I have Windows server 2016 built on ESXi 6.5.0 Update 2 (Build 829453) and I noticed slow disk performance. I have found some tips about bad working drivers of storage and tried this, but with no visible results. I tried upgrade firmware of RAID controller, Bios, iDRAC... Server is  DELL PowerEdge R230 with SAS disks.

      Windows Server 2016 Really slow on ESXI 6.5

       

      Is this problem with some bug? Or do you know what can I do to increase disk performace? Maybe update some modules?
