Cloudron Disk Speed - Optimum?

[nebulon]

indeed, my nvme only clocks in at around 500 MB/sec on my homeserver.

@LoudLemur then you need a NVMe Disk

[humptydumpty]

@nebulon me too! Any idea why it’s being limited?

A Netcup VPS

A Hetzner VPS

Yet another reason for me to do my planned "moved all my VPS servers onto a dedicated Hetzner box"

Don't understand your question here but are you asking why disk speed is lower ? What's being reported is the speed as reported by the kernel and hardware.

When you are using these two together, do you notice the difference in responsiveness much? That is a big difference but maybe the increased performance is not very noticeable.

I haven't really tested to be honest. But the one with a slower disk has lots more RAM so would be hard to compare.

@girish Nebulon's NVME speed is around 500 MB/s only, but that's SSD speeds. I'm getting the same NVME speeds on my Cloudron home server. I was using this server as a regular Windows PC before I repurposed it, and I was getting full NVME speeds, so I know it's not a hardware issue. Also, that's the speed (~450 MB/s) I get on my Contabo VPS even though I migrated to an NVME plan. It doesn't make sense.

@humptydumpty hm that makes me wonder if there are some kernel/bios/device features one needs to set on linux to enable that?

I just moved my Cloudron to Contabo VPS S with NVMe. It shows nearly 70 MB/sec on my cloudron disk usage report. This does not feel like NVMe speed at all. It's a fresh install. What should I do?

• A - run a script on the server to determine the true speed (edit: i ran curl -sL yabs.sh | bash screenshot of results see below)
• B - trust this number and complain at contabo customer service
• C - accept it as I ordered a cheap VPS
• D - installed apps slow down the disk (2x Ghost, Mealie, Surfer, typebot, umami)
• E - else

@erikscholz I've never tried a Contabo VPS, but:

@jdaviescoates said in Favorite VPS providers?:

@sentinel65 said in Favorite VPS providers?:

+1 for Contabo. UI/UX is archaic but it does the job and it does it well.

I've only tried them for the Object Storage but quickly regretted that as they don't even support virtual host style URLs, only path style, see:

https://docs.contabo.com/docs/products/Object-Storage/technical-description/

(and this post)

Also, just for reference, my 3 current Hetzner Could VPS speeds:

CPX11:

CX31:

CPX31:

And for the record my Hetzner Dedicated Server:

AX41-NVMe:

It sounds like it's very oversubscribed or abused by other instances shared on that host.

You can call support and request to be moved to a host with more IO available.

Cool bench script btw (yabs.sh)

@erikscholz
Just guessing but I doubt (D) is the problem/solution
Always worth trying (B)
Failing which (C) if or while you are in contract, then find a better one

We use hdparm for this info. hdparm -Tt /dev/sda for example. I would complain to your VPS provider, since the speed is very low.

[humptydumpty]

@erikscholz I'm on Contabo's VPS L NVME plan + Extra Storage Module. I ran hdparm -Tt /dev/sda3 and got the following:

/dev/sda3:
 Timing cached reads:   12836 MB in  2.00 seconds = 6425.92 MB/sec
 Timing buffered disk reads: 798 MB in  3.00 seconds = 265.97 MB/sec

I did: C, B, C, B (useless CS), C, C, C...

In my Cloudron > System Info > I get two different speeds for /sda3 and /sda2 (boot) partitions, 312 MB/s vs. 1088 MB/s, respectively. Again, I'll just go with C and move on with my life

[erikscholz]

Thanks for the input y'all. I did some further testing and found out something strange. When I change the CPU resources for each app, and it doesn't matter if I increase or decrease the resources and then checking the disk speed again it went up. Also wenn I stress test my website (did that with the siege command line tool) the disk speeds went up. Seems like Contabo does allocate resources when there is stress on the system and decrease resources when it's idling? So I could reach speeds of around 300 MB/s to 1 GB/s on SDA3. Same with SDA2.

I think I'll ignore the numbers for now as I don't feel there are real world problems on the VPS. And I guess if I really need to upscale performance for whatever reason I might switch to Hetzner or something else.
