session_start() causing massive slowdown?

    I’ve noticed that on some sites, I’m getting a MASSIVE slowdown in the WordPress backend (very likely since our datacentre forced retirement of older verions of PHP). While writing a plugin for a new site, I saw it begin to happen shortly after starting to use session variables and tracked it down to the use of session_start().

    Moving around the WP admin is all fine until I hit the products tab, then it takes about 5 minutes or so to load. Removing the session_start() reliably makes it all work fine.

    Now, I’m “supposedly” starting my session properly using:

    function register_my_session()
    {
    ? if( !session_id() )
    ? {
    ? ? session_start();
    ? }
    }
    add_action(‘init’, ‘register_my_session’);

    Any idea what I might be doing wrong here? I’m sure this is somethng I’m not doing right somewhere.

    WordPress ver: 6.1.1

    Oh, and for the record, as I’m using PHP 7+, the check:

    if (session_status() == PHP_SESSION_NONE)

    also has the same effect. ??

    Hi @oxfordebooks

    Thanks for reaching out!

    I understand that on some sites you are getting a massive slowdown in the WordPress back end, correct?

    There are several factors as to why a website is slowing down.

    As a first step, you might want to check if your server is using the minimum requirements to run WooCommerce smoothly since as you’ve mentioned that you are using PHP 7.3.33.

    Then, you might want to check these articles to help you troubleshoot the root cause of this issue:

    It might be worth checking as well to contact your host as they could provide you better analysis about the slowing down of your site.

    Hope this helps!

    I’ve solved this.. by brute force. Rather than using SESSION variables to store temporaty information such as checkbox states in the user-side, I changed over to TRANSIANTS. These are allready good to go at any time and it works just fine.

    Interestingly, I’d wrappered my session_start() with a check to see if we were in admin, but this then seems to cause random errors ehere WP can’t select the database in the back end (maybe some REST function?). Very odd… seems like using session variables isn’t a good idea in WP any more?

    Hi,

    Glad to hear you found a solution.

    I understand your point, please note that custom code solutions are out of scope of support in this forum. I found this article on the web that is related to your question:

    I hope this helps.
