I'd value your thoughts :-) Ken
Can't speak to your exact bottleneck here, but I think I'd try and
eliminate your disk hardware from the game for a start, to see what
happens there.
Try creating a null block device
(https://www.kernel.org/doc/html/latest/block/null_blk.html), and then
benchmark writes to that on the host and the guest. See what that does
as a baseline....
