From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It seems to me you are already looking into all the possible options besides getting a VPS with more RAM. I am a bit confused on why you are seeing increased CPU usage by the hypervisor for this though.
The server is clearly overloaded, as soon as I start using some 10% of CPU frequently for some minutes (due to swap operations), the Hypervisor starts to throttle my instance and this of course makes the thing worse with an avalanche effect. When this happens steal time displayed from top can go literally as high as 90%.
On AWS they have something called "bursting". Basically they will let you use 100% of your vCPU, but not all the time. If you use it constantly they start to throttle you. That's explicitly stated when you rent an EC2 instance (which is their VPS). Perhaps your provider is doing something similar.
Yes exactly, burstable instances it's common jargon for AWS and GCP, but applies to all major providers.
Yeah, those are great for something that will be sitting idle most of the time, awful for anything else.
Ask the provider not to throttle you then? Are you not entitled to the entire cpu?
So probably not entitled to anything from them.
I believe it's a shared VCPU intentionally, I will recheck the terms and conditions, but I think I am not in the position to claim much.
