This is pretty much a free advertisement for non-competitive pricing.
You have no idea how many neighbors you have on that vps.
And that "vcpu" is likely a hyperthreaded core, not physical, so it's a "half core" in reality.
Monthly vCPU Memory SSD Transfer
$6 1 1GB 10GB 1TB
$12 1 2GB 20GB 1TB
$18 1 3GB 30GB 2TB
$24 2 4GB 40GB 3TB
$48 2 8GB 60GB 4TB
$96 4 16GB 100GB 5TB
$192 8 32GB 200GB 6TB
At that "4 core" (virtual) pricing I'd take dedicated from OVH instead [1]
The $6 pricepoint is likely to just get you in the door for an upsell.
Why would you subject yourself to unknown neighbors with unknown abusive habits on the server resources when you can just get a dedicated with SSD for less money and co-host your own projects with known behaviors (and without the overhead of a vps hypervisor).
