Question

Network administration

Interested in the question about shared hosting, which usually have restrictions in various tariffs.
Does limiting the load on the processor affect the speed of interpretation in php and, accordingly, receiving data from the server to the browser?
Example:
25%
load Peak load per processor core cannot exceed this value.

Answer 1

If the php interpretation load does not rest against the allotted "ceiling" for the CPU, then no, otherwise it affects: the speed of the site slows down and, as a result, the speed of content delivery to users.

Answer 2

Of course it does, you executed the script at four gigahertz and another thing at one gigahertz
