I am working on a low-latency/max performance host/guest configuration for a Windows 10 VM on the Zen platform and some of the material regarding virtualisation that I have read so far indicates that using Huge Pages and disabling Transparent Huge Pages improves latency to memory. Is it possible to enable this with 6.7.0-rc5, if not, possible to add optional access to `/proc/sys/vm/nr_hugepages` for a future release?

Yes we'll look into this.  There was an issue with this back when VM support in Unraid was first being developed, which I can't remember atm, but @jonp might.

I definitely want to try testing this again however the last time we did this testing we saw zero performance difference between transparent huge pages and regular huge pages. furthermore there are advantages of using transparent huge pages that you do not get with traditional huge pages. Mainly that you don't have to pre-allocate a large chunk of your memory for permanent use with VMs.
