    Let me just say first that it's fast, but not as fast when I'm logged out. My forum loads extremely fast as a guest, but it takes some 1-4 seconds to load between pages at times when logged in as a member.

    Is this normal or is there a way I can speed it up to guest-levels?

    Would I need a higher spec server or can this be done with tweaking values after centminmod's optimized values?

    That isn't enough with your forum size :|

    At-least switch to one of this plans:

    That is normal, logged out members would have some form of caching in place if you implemented it so guests are faster than logged in members which would bypass such guest caching. Also logged in members would run up additional mysql queries and load from logged in member displayed data which guests won't have.

    But ultimately how fast logged in members experience a forum is down to server optimisation and server hardware backing that optimisation. Centmin Mod auto optimization is based on server specs and for the server. You'd have to further optimise based on your web apps usage requirements.

    I was thinking about upgrading to the $20/month plan and killing off some smaller servers I have.
    I use redis guest caching so that's most likely why, but I'm always open to speeding it up for members too.
    I originally started off with the Linode $5 plan for this server and only recompiled nginx and php. I'm guessing since the number of cores haven't changed from $5 -> $10, I wouldn't have to reinstall centminmod to get the optimized values again? Would I have to do that if I upgrade to the $20/month plan?

    Should I do a fresh install of CMM on a $20/month test server and transfer configs anywhere after upgrading my live server to the $20/month plan on Linode? How should we go about this if we want to keep the optimizations?

    For PHP-FPM on upgraded VPS at Linode, you can recompile PHP via centmin.sh menu option 5 so auto redetects memory and server resources and manually re-run /usr/local/src/centminmod/tools/setio.sh as follows
    Code (Text):
    /usr/local/src/centminmod/tools/setio.sh set
    

    which will recalculate MariaDB MySQL innodb I/O variable values to set

    i.e.
    Code (Text):
    /usr/local/src/centminmod/tools/setio.sh set
    Full Reads: 24975
    Full Writes: 59362
    
    set innodb_flush_neighbors = 0
    
    innodb_io_capacity = 2900
    
    +------------------------+-------+
    /etc/my.cnf adjustment
    +------------------------+-------+
    existing value:
    Variable_name   Value
    innodb_io_capacity      2700
    innodb_io_capacity_max  5400
    new value:
    Variable_name   Value
    innodb_io_capacity      2900
    innodb_io_capacity_max  5800
    
    +------------------------+-------+
    innodb io threads adjustment
    +------------------------+-------+
    existing value:
    +------------------------+-------+
    innodb_read_io_threads = 2
    innodb_write_io_threads = 2
    +------------------------+-------+
    new value:
    +------------------------+-------+
    innodb_read_io_threads = 2
    innodb_write_io_threads = 2
    +------------------------+-------+
    
    Restart MySQL server for io thread changes

    I know this because I think I've asked it before, but I think there was another thing that we couldn't do. Or maybe I'm not remembering correctly at 1 AM and need some sleep.

    I'm still on the $10/month plan. Upgrading from PHP 7.2 to PHP 7.3 shaved off 1-2 seconds when browsing the XF 2 forum while logged in. It feels almost the same when browsing as a guest.

    I just wished everything was compatible for 7.4.
