Cache Gravatar makes WordPress sites load faster

If you don't already know, the Gravatar in the comments section of your WordPress website will be downloaded from the server, not from your host. Therefore, even if your site is hosted on a server in the EU, it will still be affected by an undersea cable problem, especially in the case, the article has many comments. So how to solve this problem to increase the loading speed of your WordPress website? The main solution is to cache Gravatar on the host. In today's article, I will show you in detail how to do that.

Why does Gravatar affect web loading speed?

As mentioned at the beginning of the article, Gravatar is downloaded directly from's server, so you cannot compress to reduce the size or set the cache time on the web browser for them. Each Gravatar is an image, so the more Gravatars a page has, the more requests it receives and the slower it loads. Even if your website uses a host located in EU, Gravatar is still downloaded from servers located abroad. That is, the loading speed of the elements on the website will not be the same. You will need to cache Gravatar on your host to minimize their impact on web loading speed.
