For this post, I am using OpenShift free hosting with PHP v5.4.40 and MYSQL v5.5.52, and HTTP/1.1 protocol. I am using the WordPress Twenty Sixteen theme with a 40MB memory limit.

Why Openshift?

I am using it from 2014 to 2016 to host two blogs, and the performance is similar to any shared hosting.

Sometimes worst if we compare it with SiteGround.

For testing, I am using Post generated by FakerPress with Unsplash It images. Please keep in mind I do not enable any minification setting.

  1. Hello mate! For me, tweaking page load speed is always a serious matter. I have dedicated much time in evaluating plugins that claim to optimize WordPress page load speed. I know that W3 Total Cache has a very good reputation in the industry. Recently I came across two page load optimization resources, Hummingbird and Breeze Cache Plugin that I would personally recommend WordPress Community to give a try.

  2. I have stackcache preinstalled in my managed WP. Can I install another cache plugin again?

    • Shaikh Masood Alam

      I never advise installing any WordPress plugin for speed things up if your host handles it at the server level. At BlogGaani, we are using Nginx web server and use Nginx Helper by rtMedia.
      But if you still facing performance and speed issue then contact your hosting provider.

  3. WP-Rocket is the best one!
    Compression, lazy loading and cache…the support is 1+!
    I use this for all my clients and all pages loaded under 1sec.

    • Shaikh Masood Alam

      I use it too for clients but server caching helps me to get better results compared to WPRocket
