WordPress on Multiple CPU machines

  • Hello,

    I wanted to double check something that I’m trying to research (google, testing etc). But I’ve heard WordPress doesn’t really benefit from adding more vCPUs since it/and PHP is not multi threaded anyway.

    wanted to check to see if anyone had any tips with us. Mostly curious to see if can get it to use more.

    PHP is not multi threaded

    You have half of the answer.
    One PHP process does not benefit from adding more cores.
    But, more processes will reuse more cores. Here will be at least:

    1) MySQL query thread
    2) webserver process/thread
    3) if not using apache’s mod_php, PHP can be its own process
    So even for single request you utilize 2-3 cores.

    Add more clients and they will spread the load over all available cores.
    More clients – more cores. Each can utilize at least 2 at same time.

    Thanks,

    That sounds good, but in the case of a multisite, it probably won’t take advantage of this?

    Any site with visitors will take advantage with multiple CPU cores.
    More cores = more simulnateous requests can be processed without delay at max cpu power.
