    Hi all

    I am curious about the modules required or not required for a wordpress installation

    currently I have the following modules and would like to know if any can be safely deleted as it is not obvious what some do or how they are connected to each other, any help is much appreciated

    thanks

    EasyApache includes modules intentionally to provide the most secure, stable server for you. To check to see if you can remove any of them, I'd recommend looking through the documentation from both us and Apache.

    You can find our documentation on the various Apache modules here:
    https://documentation.cpanel.net/pages/viewpage.action?pageId=5767213

    You can find the Apache documentation on the Apache modules here:
    For Apache version 2.2 - https://httpd.apache.org/docs/2.2/mod/
    For Apache version 2.4 - https://httpd.apache.org/docs/2.4/mod/

    You can add or remove the modules in your Apache build with EasyApache, which you can find more about here:
    https://documentation.cpanel.net/display/EA/EasyApache

    To answer your question in a general sense, most (if not all) of the modules in that list are part of a standard EasyApache installation. Some of them you can remove, if you wish to, by deselecting them in EasyApache.

    We are also in the process of updating our Apache module documentation, so if you come across anything confusing, please make sure to let us know so we can improve it for you.

    thank you

    however most of them have confusing names, some I am aware of what they do and why they are needed, however some have no sense at all

    I am trying to trim server down a touch, but everyday I improve something I have a momentary improvement on websites loading then following back to high TTFB

    the load on server is low, mysql is optimized to within an inch of its life, so the modules is the last port of call before I bang my head on wall repeatedly lol

    thanks

    I agree a lot of the names are confusing, I'm addressing that as I am rewriting them. If you have specific ones you have questions about, I can try my best to answer them.

    Your EasyApache module selection does not look unusual. You might want to check the following things just in case:

    Mod Security rule list - Make sure it is not long, and that the rules are efficiently organized.
    The Apache error log - /usr/local/apache/logs/error_log Look for errors and warnings, as well as maybe a script that isn't operating efficiently and is making multiple calls to Apache that it doesn't need to

    Our Optimization forum: Optimization might have additional information for you.
