Linode Vultr Move from vultr to linode caused a huge performance decrease

Would love to learn about that.

 

Apparently the Linode London Gold CPU server was so new and freshly unpacked that certain distro images were not in stock.
Fixed by now.

Difficult to say and difficult to establish because you can not look at the host itself.
Every low end provider does overselling.

It is only the question of how far one and the other goes.
Without overselling you only could run around 40 single core,
VPS servers at 5$ per month per host (Dual CPU - 2 x 20 cores).

That is far too little and not profitable.
Given that only a single Linode CPU costs about $3000.
So that's around $6000 only for the CPU's per host.

There are however a few landmarks:

When you monitor your system well, you can come up with facts and report this to the provider. For example to force a transfer to another host.

 

I landed on one in Newark! From what I can tell in this specific location, if the host ID starts with h13**-cjj1 it will most likely have the newer Gold 6148 CPU.
