I'm interested in the disk I/O performance of the Post4VPS VPSs with NVMe SSD-backed storage (ie VPS-7, VPS-13, VPS-14.)

Thus can you please run the following commands on your VPS and share the output with us:

Code: (Select All)

# Your block device details
lsblk --output "NAME,KNAME,MODEL,HCTL,SIZE,VENDOR,SUBSYSTEMS"

# Investigating the used kernel drivers (virtio vs nvme)
lsmod | grep virt
lsmod | grep nvm
lshw -class storage
lshw -class disk

# Buffered Sequential Write Speed, using @sohamb03's script with the -io flag
./bench.sh -io

# Disk seq.read Speed (Cached)
hdparm -Tt /dev/vda (or /dev/sda)

# Disk seq.read Speed (Direct)
hdparm -Tt --direct /dev/vda (or /dev/sda)

# Disk Latency:
ioping -c 15 /home/mysudoer
ioping -c 15 /dev/vda (or /dev/sda)

# Disk Seek Rate:
ioping -R /dev/vda (or /dev/sda)

# Disk Sequential Speed:
ioping -RL /dev/vda (or /dev/sda)

Thanks!

I am sorry, due to the notice of withdraw of VPS 14 I have already proceeded to shutdown the machine. 

@deanhills I think we can close this thread as the discussion can't continue anymore
