Genesis 2.0b2 vs Thesis 2.1b Site Load Speed, Which Theme Loads Faster?

Many people claim that Genesis Framework loads faster than Thesis Framework, others claim the opposite thing, they think that Thesis loads faster than Genesis. Some people I came across their comparisons do funny stuff, I have no idea where they came up with their test criteria, and what exactly they are trying to prove.

Today, I am going to show you which Theme is faster by doing a very simple and quick site speed test. I will use Pingdom Website Speed Test.

To start with this test, I’ve created a fresh WordPress installation, and I installed Thesis 2.1 beta and Genesis  version 2.0-beta2 on the same installation, same web hosting server, and without any additional plugins or content. I did nothing special on that site, it’s just a brand new blog that has the default setup. By this way, I will guarantee fair test for both frameworks as they both will run in the same exact environment.

So, let’s start with Genesis, then test Thesis.

Genesis 2.0b2 Site Speed

I ran the site load speed 4 times and took screenshots of the results, I did it 4 times because test gives different results, so you can take a look and do your math. And, here is what I’ve got:

First Genesis site speed test

Second Genesis site speed test

Third Genesis site speed test

Fourth Genesis site speed test

Thesis 2.1b Site Speed

I’ve done the same exactly with Thesis, so here is the 4 site load speed tests:

First Thesis site speed test

Second Thesis site speed test

Third Thesis site speed test

Fourth Thesis site speed test


If we calculate the averages, it comes out as the following:

  • Genesis average load speed: 786.75 ms.
  • Thesis average load speed: 551 ms.

As you can see, Thesis loads faster than Genesis! However, both Frameworks average load is under 1 second, which is a great thing.

  1. Great experiment buddy. Just wondering what “lacks” for those performance grades to go up? I mean, the speed is there.. So, what else is missing 🙂

  2. Yes, they both are very fast loading frameworks and so are some other out there on a naked site.
    I don’t think the bare site load speed is relevant anymore as the average user use 10-15 plugins on a WordPress site, plugins that will slow down the site. On the other hand there are methods to speed up a site and at the end of the day a “bloated” site could load faster than a skinny site.
    I do prefer Genesis over any other framework for reasons that are widely known. I do not use Thesis anymore since version 2.x as I don’t understand how to use it. For me Thesis2.x just does not make sense.

  3. Hi Hesham,

    Thanks for sharing the info. I always thought Thesis is slightly faster than Genesis. Guess I was right but am using Genesis (weird me)!

    Anyway, appreciate you take the time to do the testing and this would be great for others. Definitely going to share this info.

    Thanks for everything!


  4. Nice article Hesham. I review products, so I need a fast framework. Both are fast, but I am going with Genesis based on other peoples recommendations (I am a developer too).

  5. Hesham,

    Thanks for putting some hard metrics out there.

    I have a semi-related question. You are surely familiar with Google Page Speed.

    I run Gensis on one site, and Thesis 1.8 (haven’t yet upgraded) on others. With either site, I get the following notification from Page Speed: “Your page has 1 blocking script resources and 3 blocking CSS resources. This causes a delay in rendering your page.”

    Isn’t there something wrong with those themes in that they control the blocking scripts” which are causing the delay?

    Thanks for your thoughts.

    • Based on my understanding, the blocking scripts or CSS is those that are rendered before the page (started to render and) show up.

      I don’t think there is something wrong with that, but the best practice is to see which scripts can be loaded after page display (for example: when you load scripts in footer).

      P.S. There are notes in Google Page Speed that may explain more details.
