ZFS + KVM + NTFS Benchmarking Various Record Sizes


This benchmark aims to identify optimal combination of record sizes (i.e., recordsize for ZFS, cluster_size for QCOW2, allocation unit size for NTFS) for a Windows 10 Guest VM running on top of ZFS + KVM.

Host: Dual Intel Xeon 6130 @ 2.10GHz, 384GB RAM, CentOS 7.6 Virtualization Base Environment, ZFS 0.8.0 via EPEL zfs-testing repository

ZFS Config: 4 x RAIDZ2 (5 x 8TB 7.2K HDD) + 2 x OPTANE 900 280GB SLOG MIRROR + OPTANE 900 480GB CACHE

Windows Guest: 2 vCPUs, 4GB RAM, 40 GB QCOW2 (bus:virtio, cache:writeback, io:default, cluster size 4k ~ 64k)
