New host build, very slow VM performance

Hello,

 

I have a new build I just put together and am running ESXi 6.7 + vSphere 6.7 - just updated ESXi with latest updates from https://esxi-patches.v-front.de/ESXi-6.7.0.html

 

The system is performing extremely slow.  I am making my first VM, Windows 10 1803, and the speed reported in vCenter is 600 MHz.  And it really feels like it, too.

 

My system:

Supermicro X10SRL-F motherboard latest bios (3.1)

E5-2650 v4

2 x 8GB DDR4-2666MHz RAM 1rx8

Samsung SM953 NVMe datastore

running off USB to boot

 

I'm noticing as I write this that I am only using 2 DIMMs in a system with 4-channel memory.  I have more memory coming soon, so hopefully that will improve things.

 

But it's hard for me to believe this is all because of using two DIMMs instead of four.  Is there some sort of setting maybe in the VM or in vSphere that can be tweaked when the processor is clocking so slow?

 

Thank you

Avery
