FIO NVMe Disk-Benchmark for 64k-Performance (MSSQL Server)

fio-benchmark-nvme-64k-mssql.cnf

# TO RUN:
#   apt install fio
#   add the config-file on your target system
#   replace '/dev/nvmeXn1' with either:
#     the path to a block-device you want to benchmark (examples: /dev/md1, /dev/sdb, /dev/nvme2n1, /zfs_nvme [or whatever zfs mountpoint you use])
#     the path to a test-file on a mounted partition of ZFS-volume (performance will most likely be worse than on the block-device directly)
#   start: fio test.cnf

# NOTE: You might want to lower the iodepth and numjobs to the point where you do not see any improvement - we just eye-balled it
