Improved PageSpeed Score but not the Fully Loaded Time in GTmetrix

  • I was playing with this plugin. In GTmetrix, it seems to improve the PageSpeed Score (from 87% to 91%) but the Fully Loaded Time hasn’t made much difference.

    I tried both async and defer for javascript and jQuery was set to ‘Excluded’.

    Fully loaded is pretty irrelevant, look at “first paint” and “onload” instead?

    Here are some details.

    With Async Javascript disabled:
    PageSpeed Score: 87%
    Fully Loaded Time: 12.5s
    TTFB: 3.3s
    First Paint: 5.9s
    Onload: 10.5s (4ms)

    With Async Javascript enabled:
    PageSpeed Score: 91%
    Fully Loaded Time: 14.4s
    TTFB: 3.3s
    First Paint: 7.2s
    Onload: 12.3s (5ms)

    • What is the difference between Fully Loaded Time and Onload?
    • Isn’t Javascript defer supposed to reduce the TTFB as well?
    • What is the value inside the brackets in Onload?

    well, if I were you I would not use AsyncJS in that case ??

    TTFB is not impacted by how JS (or CSS) is loaded no.

    re. fully loaded vs onload see https://gtmetrix.com/faq.html#faq-fully-loaded-vs-onload ??
