    Please fill in any relevant information that applies to you:
    • CentOS Version: i.e. CentOS 6 64bit
    • Centmin Mod Version Installed: 123.09beta01
    • Nginx Version Installed: nginx/1.13.1
    • PHP Version Installed: 5.6.30
    • MariaDB MySQL Version Installed: 10.1.24
    • When was last time updated Centmin Mod code base ? :
    • Persistent Config: LETSENCRYPT_DETECT='y'

    I have a weird issue with a fresh box, installed about 10 days ago.

    I could make a WP site go very very fast with GTMetrix without SSL (Let's Encrypt), getting 84% PageSpeed and 94% Ylow.

    But same site using SSL is getting 77% in PageSpeed and 60% in Yslow.

    Test URL is https://paymes.katxe.net/

    How can I improve SSL side ?

    Browsing you can feel fast response in non SSL, but ultra slow with SSL.

    I didn't tweak much config neither tweaking, but before starting to touch I would like to know what would be the main issues where to attack.

    Thanks :)

    Nginx 1.27.x
    MariaDB 10.x/11.4+
    gtmetrix shows 2.52MB size page so yes it will be slow regardless - don't look at the score by itself look at metric, stats and page load times and TTFB and initial page render times

    use webpagetest.org for more accurate testing

    also your non-https site is actively using wpfc minification while https isn't it seems

    the wpfc minification on non-https version means time to first paint and initial render time is faster than https version

    Cut page size from 2.5+ MB to less than 500-900KB for optimal page speed

    It was an issue generated by the caching plugin.

    Seems that I was using non SSL in the admin WP panel.

    After disabling in non SSL mode and enabling in SSL mode, all changed positivaly :)

    What I didn't get is that all let's encrypt SSL auto certs are giving issues, i guess it's a root cert issue ..... but didn't have time to analyze and report it in here.

    I need to explain this ..... pingdom gives SSL error all the time ! :(
