phoronix-test-suite benchmark 1803243-KH-1803231TY84 ZFS SSD Benchmark: RAW IMAGE vs QCOW2 vs ZVOL for KVM - Phoronix Test Suite ZFS SSD Benchmark: RAW IMAGE vs QCOW2 vs ZVOL for KVM This benchmark show’s the performance of a zfs pool
providing storage to a kvm virtual machine with three different formats:
raw image files on plain dataset
qcow2 image file on plain dataset
zvol
For each of those several filesystem benchmarks from the phoronix-benchmark-suite are run with two different recordsizes:
8k
64k
Host Details:
cpu: Intel® Xeon® CPU E5320 @ 1.86GHz
ram: 6GB DDR2
sata: Intel Corporation 631xESB/632xESB SATA AHCI Controller (rev 09
os: Debian GNU/Linux 9.4 (stretch), fully upgraded as of 2018-03-15
zfs: 0.7.6-1~bpo9+1 (from stretch-backports)
ssd: 2x samsung 840 pro 256GB
KVM machine:
cpu: host
ram: 1024MB
disk: bus=scsi,cache=writeback,io=threads
os: Debian GNU/Linux 9.1 (stretch)
fs: ext4
The zfs pool used consists of a single mirrored vdev with samsung 840 pro ssd’s.
Each benchmark is run like this:
drop all caches
trim whole ssd’s
create zfs pool (ashift=13,compression=lz4,atime=on,relatime=on
benchmark,devices=off,exec=off,setuid=off,xattr=off)
create disk:
qemu-img create -f raw debian9.raw 50G
qemu-img create -f qcow2 -o cluster_size=8k,preallocation=metadata,compat=1.1,lazy_refcounts=on debian9.qcow2 50G
zfs create -o volblocksize=8k -V 50G benchmark/kvm/debian9
create kvm machine
take timestamp
let debian9 install automatically
save install time
install phoronix-test-suite and needed dependencies in the vm
run the pts
trim the filesystem and save the time it took
copy the results to the kvm host
destroy vm and zpool
