Kamatera vs. Register.com 2020

migration from Contabo to my own physical server that will be port-forwarded to public network using OpenVPN, so the main task of the VPS is to route traffic to different Virtual Machines on my physical server with the highest performance.
I really like the fact, that they give 4 options of CPU rental. Most important are two options:
A: Availability - using VPS with A-Type vCPU I noticed slow performance, because of low VM Priority, so there was resource expropriation occuring.
B: General - you rent whole core of the CPU, so you can use 100% of your CPU Core. The performance difference between A and B is huge.
The difference in price is directly proportional to performance difference.
Network - I chose an option 10gbit/sec with traffic limit 5TB/month. I am not sure if this is up to 10Gbit or dedicated 10Gbit, but I guess this is "up to", because it is a bit slower...
During this review I performed a speedtest. Results (Frankfurt):
Ping: 1,373ms
DL: 2.5Gbit/sec
UL: 4.2Gbit/sec
I think these results are very good, network capacity for physical server is 1gbit.
Support is great! I had some issues, they are very helpful, every client has their personal contact person - this is amazing!
I really recommend this company.
-1 star in features for lack of System Reinstallation Option. I failed with network configuration and lost access to server. I created a ticket to support to re-install software and I was told I have to remove VPS and then create the new one. I do not know how this kind of actions is being billed, because I was in the trial period. Also, I wanted to add 2nd SSD Disk for backup storage - I am unable to do it. I can only expand it, but I need another disk/partition... So - once again - seems I should remove VPS and create new one. But I will not do it... Pity
Currently there is a subdomain vpn-prod.stelmaszyk.dev, but it's gonna be changed once migration via pre-configured VPN will be completed.

t needs to contact them and wait endlessly to hit a wall. If you want to change account holder there is no warning that this will put an automatic 60days lock on the domain.
