Cloudron Disk Speed - Optimum?

[LoudLemur]

Cloudron works best with a faster disk speed. Some report that a fast disk is particularly important for NextCloud. Perhaps there are some other applications which benefit, too.

I would like to gain a better idea of how fast a disk should be to have Cloudron work at its best. I have a small, light usage Cloudron in mind, but others might like to know what is needed for much larger installations. Also, which metric is the most appropriate to use? Random read/write?

Here is a recent tier-list as a guide:
https://www.tomshardware.com/reviews/best-ssds,3891.html

Best overall:
Transfer Interface/Protocol: PCIe 4.0 x4 / NVMeSequential Reads/Writes: Up to 7,450 MBps / 6,900 MBps

Fastest:
Transfer Interface/Protocol: PCIe 5.0 x4Sequential Reads/Writes: 10,000 MBps / 9,500 MB/s

Best Value:
Transfer Interface/Protocol: PCIe 3.0 x4 / NVMeSequential Reads/Writes: Up to 3,500 MBps/2,700 MBps

I am getting about 450MBps on my disk. Can anybody brag a slower speed?

The demo cloudron works just fine with much lower speed:

@girish Hey, that was a good idea! That Cloudron has quite a lot of use, lots of people on it and loads of applications running, and as you point out, it does really well on a much slower disk! Is that an SSD?

[girish]

@LoudLemur yes, it's on linode

I have a VPS at netcup:

My home server

I want this!

[nebulon]

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

[lukas]

@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.

[nebulon]

@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:

+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)
