dsm speeds - any ideas ?

[mbu10]

 

So i have 3 esxi server 6.7 2 of them have local storage (nvme- and SSD ) lots of ram etc all with Intel x540 or x520 (copper) all connected to the x4 pcie gen 3 adaptors

 

so wanted to run a virtualized DSM and get some decent speed

 

so i ran some test and not getting a throughput i would expect, these disks are thick enabled 

 

took lots of screenshots of the setup and the speeds at different tests to rule stuff out

setup clean windows 10 build with all tools installed
