It all depends on the package you decide to rent. A more affordable package will have less CPUs. Our packages range from two vCPUs to 16 vCPUs. A vCPU is a Virtual Processing Unit. One or more vCPUs are assigned to a VM. Each vCPU is seen as a single physical CPU core by your server's operating system.
Larger packages naturally include more vCPU's, however, the CPU is very often not a limiting factor. In the majority of use cases, the most important factor is how much memory (RAM) is needed. Modern PHP/MySQL scripts often use a lot of RAM, so RAM is very important when deciding which package you buy.
