    All depends on what you are doing, small amount cpu/ram works fine in
    lab environments as you usually don't have 300+ clients trying to write.

    My CEO found the solution, the issue of the Wordpress sync by glusterfs
    was... millions of small files made from Wordpress! :D

    If sometime we delete these files the cluster works well!

    We understood it because if we did a simple df -h on /var/wwww/ and the
    node went down!

    So... I'm sorry, glusterfs you wasn't the guilty! :D

    Maybe if you delete WordPress altogether, your site would work even
    better ...

    IrCOve been setting up WordPress for a client, and itrCOs funny how sluggish it is, immediately after you have got it going, before you have even done
    any actual work with it.

    Shared hosting most likely? Usually it is possible to give your WP
    instance more CPU power for a couple of bucks.

    Nope. Dedicated in-house VM, on pretty decent hardware (lots of RAM
    and disk, CPU cores in the dozens) under XCP-ng. There are other
    company intranet apps running on other VMs, written (by me) in both
    PHP and Python, and they all work much more snappily than WordPress.

    It's not that much about how much the host machine has, it's how much
    you assigned the VM and of course if you have over provisioned

    There are other
    company intranet apps running on other VMs, written (by me) in both

    Are they at the same size and as much db dependent as WP?
    Also the database may be the bottle neck, as I don't know anything of
    your setup it's difficult to just say what could be wrong...

    There are so much more that can be different in a VM compared to run it
    on bare metal, for example memcached had big issues some years ago when
    run in a VM, it just was extremely slow, on a smaller bare metal
    instance it was snappy as hell. The reason was how the memory was
    handled in the by the virtualization.

    Database-dependent -- several of them are quite heavily so.

    Same size and complexity ... obviously not.
