"There is no way for the primary service (such as a web server) to get priority on the system, leaving everything else (like the SSH console) as a secondary priority" - Can't we use the nice command (nice +n command) when these process are started to change its priority? I am sorry if it is so naive question
He probably meant that from a TCP point of view, as in there is no way to give a higher priority to incoming TCP connections going into the server than to those going into SSH, even if you could use nice to assign more cpu time to your server.
Or perhaps he meant that the infrastructure used to do multitasking still have to interrupt both his server and SSH, but then described how the kernel can be set to leave some cores free of work then to set the server to use only those and then run absolutely uninterrupted.
Not the only bizarre and confusing statement he wrote, anyways.
