Support » Plugin: Swift Performance Lite » Works great on desktop, not on mobile

  • Resolved mbruno909


    Hello all,

    I had great results optimizing our site with Swift Performance Lite and am considering upgrading to the full version. However, when I started testing the mobile version of the site, I was seeing a very different story.

    Using GTMetrix as an example (although the issue is confirmed across several testing sites), speed and efficiency is greatly improved on the desktop site.
    Desktop site, Swift Performance OFF:
    Desktop site, Swift Performance ON:

    However, on the mobile site, things are almost entirely unchanged. I’m especially suspicious of the fact that both number of requests and the YSlow are exactly the same as the un-optimized desktop site. It seems that Swift Performance isn’t doing anything at all (aside from reducing the page size by a measly 30kb)

    Mobile site, Swift Performance OFF:
    Mobile site, Swift Performance ON:

    With mobile speed becoming more and more important, I would like to make sure that I can get Swift to produce results on our mobile site before we go pro.

    Does anyone have experience with this issue or something similar? I tried searching the forum, but I did not find anything that seemed relevant.

    Thanks so much for your help,

    Websites’ scores don’t matter.

    PageSpeed insights tool is infamously inaccurate. Use Pingdom to test your speed.
    Pingdom check ‘realistic’ page speeds. The same speeds that a visitor would experience (with some delay depending on the test location). GTmetrix does full load, so including all the scripts that are running in the background.

    Swift is using more aggressive optimization/preload functions than any other plugin on the market. That makes it better and faster, but keep in mind, there is no one fix tutorial that suits for all websites as there are thousands of different setups, themes, plugins and combinations. If you want to make improvements, you need to configure Swift further and probably make some changes to your website, to make it more suitable for mobile visitors.

    You could consider buying our pro version, as it comes with non questionable 14 days refund policy and you have unlimited access to our support desk and one year of free updates.
