What is your disk driver? You can change virtio and to others as well on your SolusVM or Virtualizor control panel, try to changing it. It may help.
Are any other members with a VPS 4 also experiencing this issue? From what I have seen there are no current issues with the provider that would result in this. It may just be that another user on the node was utilising the disk heavily at the same time as you were running the test?
@cw1998 : I ran daily (relatively speaking) tests on different OSes always 20-50 mb/s

1st - We have limited the Free VPS (small pakages) usages to certain % .

2nd - Its SATA Disk . Every one like you testing disk IO and lot of other things (testing) its effecting the disk performance .

If you need high performance disk or you really need high performance IO , you should consider SSD VPS .
@MichaelW which disk driver are you actually using? You still haven't answered that question. Is your disk device starting with /dev/sd*X or with /dev/vd*X?

sd*X = IDE drivers
vd*X = Virtio drivers
*X = drive letter and no #. of partition such as sda1, vda1 and so on

I would also recommend you to run hdparm as I recommended the users here: https://freevps.us/thread-19948-post-223...#pid223801

Wait why is 20-50 mb/s a problem on a free vps? Are you expecting raid 10 ssd here?
Going to close this thread in 24 hours or so if there's no reply from the author to the question asked about disk drivers. You also said you got from 20-50MB/s in your testing. How often was it closer to the 20 side of that range?
sorry for the late reply,

The disk driver is IDE drivers

There apparently must have been some others users have excessive disk usage,
I am marking this thread as solved as the disk I/O is now averaging at 75Mb/s

Thanks everyone.
