WordPress very slow pre-loading / TTFB

    Hello,

    I’m using latest WP on a custom installation (shared hosting by OVH, btw), with child theme + about 15 plugins + mu-plugins; all are strictly necessary, by the way, for site functions and features. All my customers say that website is very slow on first load, I suppose is a critically slow TTFB so I made some test and there is the results:

    Take a look to the first, yellow line: what is happening here? I really cant understand that; btw, is not plugin related, I tried to disable and it’s the same.

    Is there a way to act on this aspect specifically? Could be my server so bad? Meanwhile I’m trying to install on another hosting. Any help or suggestion / hint would be appreaciated, thanks in advance

  • If the TTFB is the same with all plugins deactivated and a default WordPress theme activated (e.g. Twenty-Seventeen), then it’s straight to your host with those results as it sounds like a server issue (overloaded? oversold?).

    There’s space for improvement, first of all image-wise. https://gtmetrix.com/reports/cipiaceoriginal.it/0HqkstAu
    I’ve also encountered several server failures (500 or error establishing database connection) before I’ve managed to pull that speed test, so that server is certainly unstable.

    Hi and thanks for help.

    Image optimization will be scheduled in next days, this could help a little I suppose: photos are cropped and cached so this could influence performance, but problem basically remains.

    I also found something slow happens in first and/or second line of WP bootstrap:

    //wp-blog-header.php lines 12-16
require_once( dirname(__FILE__) . '/wp-load.php' );
wp();
require_once( ABSPATH . WPINC . '/template-loader.php' );

    Any way for detailing this better? It would be great to find/trace the precise issue.

    AFAIK optimising images and addressing the loading of bootstrap will only improve the speed once contact has been made with the server. It still looks like your server is the issue: WebPageTest results

    I’m trying to replicate same website on another web-hosting, will post results asap.

    Hi again, new test just made, I’m finishing uploading images via FTP but results seems better…

    new test

    It is the same website on a free hosting, this seems a little weird (??!), meanwhile I notice “wait time” reduced to just a second. Think will change hosting very soon ??

    That tells the story clearly. I’d show this to your host and request a refund, or a move a more responsive server. Might be worth thinking about another hosting solution if there is no improvement.

    If you’re looking for new hosting (as you apparently should) head to https://www.webhostingtalk.com and spend some time reading.

    That’s a great idea, I’m just doing that. Hope change would be useful, finally.

    I had some better results optimizing wp_options table, little hint for others having same issues.
