I ordered a VPS at Contabo today, these are the specs (screenshot https://imgur.com/a/yIKzV)

  • Quad Core either Intel® Xeon® E5-2620v3, E5-2630v4 or 4114
  • 12 GB RAM (guaranteed)
  • 300 GB Storage (100% SSD)
  • 100 Mbit/s-Port

I've now set it up, and it is running an IRI node on it.

I feel a bit strange because of the CPU steal time

enter image description here

Green is idle, orange used, the white band at the top is the steal time.

You see two peaks. The first one is when I stopped IRI, then I let it turned off for a minute, and started it again.

This is what /proc/cpuinfo looks like

power management:

What does this say about the server? IRI is running inside Docker, it has the latest Kernel (GNU/Linux 4.4.0-104-generic x86_64) on Ubuntu 16.04.3 LTS

I have another node running in VirtualBox with Ubuntu as the guest and Windows 10 as the host with a low power Xeon CPU. No matter how much work you throw at the CPU's, there's never a steal time to be seen (only one VM running)

Is this something to worry about, or even a slight ripoff? Or is this normal?

  • Is this about the subject of Iota or more of a hardware issue only related to Iota coincidentally? Dec 22 '17 at 14:38
  • About suitable vps-providers for a node. Maybe serverfault would be a more appropiate place.

  • That's what I was thinking. Dec 22 '17 at 14:45
  • Can you move it over there?

    @RobertCartaino: You have migrated this to [meta.sf], so I had to reject this. That said, I've no idea what OPs question actually is and I somehow doubt this would qualify as a question regarding system administration in a professional/business context anyway.
