Extremely poor Disk I/O (22 MB/s) on Performance NVMe VPS at Hostbrr - Ticket #8810998 - 36h+ No R
Hi everyone,
I recently signed up for a DE-Performance-4GBrr plan, expecting the NVMe Gen4 performance advertised. Unfortunately, the experience has been quite disappointing so far due to extremely slow disk I/O.
My system feels sluggish, and after some testing, I found the bottleneck:
Disk Speed: I'm getting around 22-30 MB/s (Tested with: dd if=/dev/zero of=testfile bs=1M count=1024 conv=fdatasync).
I/O Wait: My top output shows 98% wa during these tests, meaning the CPU is essentially idling while waiting for the disk.
I opened a support ticket (#8810998) more than 36 hours ago, but I haven't received any response yet. Since this is a "Performance" plan, 22 MB/s is unusable—it's performing worse than a legacy HDD.
@labze – Could you please take a look at this? I would really like to get this resolved, either by fixing the current node or migrating my instance to a healthy one.
Thanks in advance for your help!

Finally someone bringing up the issue in spotlight, for me the hdd performance on one of the server was less than 25MBps(poorer than dedirock's cheapest storage servers).
The timezone gap and very slow response (taking weeks for a reply) killed the thrill to continue
Thanks for confirming, @rohitsingh1333. It’s disappointing to hear that this is a known issue and support takes that long. A 'Performance' plan should never dip below 25 MB/s. Hopefully, @labze can clarify if this is a temporary node issue or the new standard for their NVMe drives.
Yep, same. This is why I canceled both my Hostbrr non-storage servers.
I'm paying 2eur/TB for the storage server, and yet I still getting speeds of at most ~10MB/s for it. Outrageous. Only thing I'm waiting for is the patience to research alternatives.
I wouldn't be complaining if I were paying LET prices, but I'm not.
I had a VPS from them a while back with the wrong storage – an HDD instead of an SSD/NVMe. This sounds similar to me.
from their cpanel shared hosting i got smtp issue, no response more then 24 hour +
The thing is, labze is the one man army, taking care of everything, I know it can get busy to balance life but that is when assistant staff comes to help.
The response times are longer than I'd like them to be, no doubt about that. These are some very busy days.
But do note that (unfortunately) response times are delayed when tickets are bumped as it is pushed back in queue.
The tickets should be answered and solved this evening
i have critical issue, please response Ticket #7493884
Update: Philip from support reached out and migrated my VPS to a new node. However, the speed is still stuck at 60 MB/s. It seems the issue might be deeper than just one overloaded node. Waiting for further investigation.
Isn’t brr standards is not the same as with hostfart? Paying bellow peanuts, getting fat ass hdd space - dump barely legal content and enjoy
Same here. 22-25MB/s. Germany storage box.
options? maybe with s3 functionallity.
20 MB/s is not utter crap and certainly not HDD like. But I agree, "performance server" and "NVMe Gen 4" seem to suggest high performance.
But still, if I'm not mistaken we are talking about a really cheap VPS here so adapt your expectations.
But 36 hrs (or even more) time to support response indeed is yuck. But then, what do you prefer @labze to do: discussions on LET -or- solving problems?
Not only that but it seems to actually be a really cheap storage box. 20 MB/s might not be the world but it still equals pushing/pulling data at about 200 mbit/s and i figure storing/retrieving data is what storage boxes usually do.
Admittedly if someone uses the storage to backup some large server(s) on a nearby gbit port maxing out at 200 mbit might be a little annoying but for a lot of use cases it should be perfectly sufficient. For example my personal internet connection doesn't go anywhere near 200 mbit and if backing up 1GB of data from a server takes 50 seconds instead of 10 it is probably not the end of the world either.
Edit: Guess i had OP mixed up with someone else. Still i am not entirely sure what kind of use case would constantly shuffle around that much data to make 20 MB/s into a disaster on a cheap box. Maybe Minecraft or something like that?
.
Modern HDDs with 7200RPM easily go around 200-300MBps in RW speeds. Even with RAID 6, the performance should not take that much hit. There are providers on LET which quote similar RAID redundancy and easily go 250-300MBps on 1m fio.
Getting 20-25MBps in 1m fio is brutally slow and takes us to the age of floppy disks.
Whats the need of having 1gbit/10gbit network port when the vps is not capable of going even above 200mbps, it just disappoints the people who think they have grabbed an extremely rare server(which used to be true tho).
Well, that might be the case but in the end its shared hardware. 300 MB/s = 15 users concurrently hammering the disk at 20 MB/s (obviously assuming there is fair distribution of resources). Sure sometimes the stars align and 90% of all neighbors are LET users running YABS once and letting the box idle afterwards but if not and 5 people aren't sufficient to finance the node and turn in a profit... well...
This is nowhere near the speed of a floppy disk. Trust me, i know. It is more like the speed of an aging (and overall unimpressive) rust spinner. Not exactly great but on average probably still quite sufficient. Admittedly i get how the term "performance plan" might be a bit frustrating in this context.
That is pretty simple: To be able to burst if there is actually enough resources available at that time. Wouldn't you hate to know that the node you are on is sitting at 50% idle but you are still stuck at 100 mbit/s because someone decided "There shall be no network adapter rated higher than the absolute minimum bandwidth available!"?
Yeah, the lowend VPS market can be a bit brutal at first but this will go away over time. People slowly learn that if a deal seems almost to good to be true (i am mostly guessing here since i don't know the exact price of OPs plan but from what i get HostBrr often times seems to run on pretty low margins) it being actually true is more of an exception than a norm and that if they want dedicated resources available to them 24/7 there is products containing the term dedicated, which might not be as cheap but, well, dedicated.
