I use virtio with the cache set to none on KVM. I get 57s on Host (16
threads, 64GB RAM, single SSD storage, using -j4) and 69s in a VM (4
threads, 8GB RAM, virtio is on the same SSD formated ext2, using -j4). Not
sure if these metrics are helpful for anyone or not, but there you go.
Go n-éirí leat,
