It is difficult to compare the speed of loading a Joomla versus a WordPress website. Site speed does not necessarily depend on which CMS you are using because frankly, both are extremely popular options that have proven to have excellent site performance. Instead, the latency rate for a user on your website would depend on the number of plug-ins you want, the type of animation or other visual design you have, or other functions that are running in the background. Rather than measuring the speeds of Joomla and WordPress, there are a handful of other differentiating factors such as usability, SEO, and overall costs.
