No. Just because you get 8 vCPU on Linode does not mean you have 4x the CPU. You share those 8 vCPU with dozens or hundreds of other servers (depending on VM size). More small slices of a pie that is the same size, is not really more.

On Linode it is never hundreds. "On average, a Linode 512 host has 40 Linodes on it. A Linode 1024 host has on average 20. Linode 2048 host: 10 Linodes; Linode 4096 host: 5;"

On the other hand as far as I know DO don't tell how many VMs share a host.
