Hetzner VPS, how do CX and CPX plans compare?

My forum was running on a CPX31 (discontinued), and I rescaled to a CX43.

Plan Name Processor vCPUs RAM Disk Space Price / month Additional info
CPX31[1] AMD 4 8 GB 160 GB 15€
CX43 Intel® / AMD 8 16 GB 160 GB 10€ :warning: Limited availability

My database is 23 GB and the forum is active daily, but niche.

My performance test is very… Let’s say, crude, but I guess it’s enough to see if the new plan is a good fit for my forum or not :smile:

I reloaded the home page 20 times and calculated the median loading time.

CPX31 CX43
Median loading time 523 ms 876 ms

And indeed, the forum feels slower to browse.

Despite the higher specs (double RAM and vCPUs) of the CX43, the low availability seems to be harming the loading time a lot (which is what matters most as a user). It might fluctuate over time so I won’t change to another plan right away, but in the meantime, I think it’s always good to know.

If you tried CX Hetzner’s server plans, please let us know your experience :slight_smile:

  1. The newer plan, CPX32, has same specs but is 3€ cheaper. ↩︎

Interesting. My home page load is about 400ms. I’m using CAX11, which is ARM based, and has only 40G storage. My compressed forum backup is only 1G. So, a much smaller forum, therefore perhaps faster load.

I would guess ‘limited availability’ means that Hetzner do not have many machines of this spec available. I wouldn’t expect any implication about performance.

Ah, yes, you’re probably right, I misunderstood.

What they say about CX plans is rather:

Because these shared cloud plans divvy up CPU resources, they are ideal for development and testing environments, blogs, forums, CMS, small databases, and VPN servers.

(Hetzner introduces new shared vCPU cloud servers)

Cost-efficient on older hardware generations, with limited availability. Ideal for variable workloads that can handle changing CPU performance. Optimized for low CPU usage with variable workloads.

(backend)

Optimized for cost efficiency, available only in limited capacity.

(https://www.hetzner.com/cloud/).

So it’s more like they use older hardware if I get it right. Observed forum speed is kinda disappointing anyway :thinking:

One thing about shared machines - and they always are shared - is that the other tenants might be very quiet, or very active. If they saturate the i/o, or use lots of memory bandwidth, you get a fair share, but that’ll be less than if they were quiet.

Yeah let me say something I’m watching a forum that using cloud too so maybe this be the big trouble for high traffic specially them that is was had many outages this month

I’m self-hosting using bare metal + virtualizor, you could try OVH or idk
