Wordpress is a great CMS that I began to use three years ago and used to create this website. However as I'm student, my website is hosted at Online.net at the cheapest offer and as the performance of the servers are quiet low, I decided to redo my website under the CMS PluXml which is lightweight.
Before to continue this article, I have to mention that at the same time I updated my website, I got to know that Online changed their shared-hosts and they are much better now. By the way, the statistics in this article are from the old servers, when I could compare both Wordpress and PluXml on the same server.
So as my Wordpress website was pretty slow (webpagetest.org displays a time of 11.633s for a fully loaded page), as for a long moment I had database connection errors with my shared-host and as some parts of the website didn't suit to me anymore, I decided to try PluXml. PluXml is a French CMS which is very lightweight and offers the basic functionalities for a blog. It's particularity is that it doesn't use a database but stores the data in XML files.
Once my website finished, I uploaded it on a sub-domain of the same shared- host than the Wordpress website to see the difference in performance. I made the tests with webpagetest.org and as you can see, it is astonishing (in red the Wordpress, in blue the PluXml):
If you wish, you can see the details of the requests for each website at the end of the article.
So what can we say about this ? At first, the website on PluXml with 1.8s is extremely faster than the one on Wordpress with 11.4s. But we have to take a closer look to understand:
So can we compare the two websites ? Yes, because even if I didn't put the Twitter widget again on the website, in overall the content and the design of the two websites are pretty much the same.
I'm pretty happy I made this choice and to see that it was very efficient. PluXml is quite easy to use but you need to have good knowledge in HTML and a little of PHP. I think in some cases it can be a good choice but if you need a website more complex than just a blog I will recommend you to take Wordpress again.
And you, do you want to give it a try?
For the curious, here are the details of each requests:
