Optimum Gravatar Cache

説明

Optimum Gravatar Cache allows you to create a local cache with optimized copies of gravatars. The optimization is accomplished by resizing the avatars to the sizes used on your site, in addition to optimizing the images internally. Optimizations are performed to minimize the size of each avatar served by the plugin.

The plugin uses WordPress CRON to perform heavier tasks. Avatars are resized in the background. Avatars are optimized internally in the background. Except in certain cases where it is necessary to resize the avatars in the page request.

The plugin handles all your site’s gravatar as long as the wordpress get_avatar() function or buddypress bp_member_avatar() function is used. Works with plugins, themes, etc.

The plugin allows you to customize the avatar by default. This avatar is served whenever the user / visitor does not have a custom gravatar. This greatly reduces the number of requests made by your page, improving the user experience. Besides allowing to frame the avatar by default with the theme of your site.

The plugin, after being configured and activated, starts by serving gravatar for all. And it begins to create the cache dynamically in the background with the sizes being collected by the requests, as well as those configured on the plug-in page. When the avatar already exists in the cache, the plugin serves the avatar in cache. The plugin periodically checks to see if the user updated their gravatar on gravatar.com if yes is updated locally. This way, keeping an updated cache.

The plugin intends the following:

  • Work with the gravatars locally, cache;
  • Reduce the number of requests per page, thus reducing the total time required to load all files. This is achieved because most users do not have a custom gravatar, and for those, only one file needs to be downloaded;
  • Optimize all avatars by reducing their size and transfer time again.

Please if you find any bugs of any kind please contact me so that I can solve it as soon as possible.

Dependencies

This plugin depends on the following PHP modules:

  • php-gd or php-imagick (So that it can resize the avatars)
  • php-curl (So that it can communicate with the gravatar using the same connection to update several avatars)

The plugin also depends on WordPress CRON to be able to solve the heaviest tasks in the background.

It just works, unlike other plugins that are supposed to do the same thing. It has great options too for adding a custom default avatar if you don’t have one already, and even Lazy Loading for the Gravatars (with a custom loading image option too). After testing on multiple sites, it seems to save almost .1 seconds for every 20 comments, which was way more than I was expecting. Those Gravatars really can slow down your site without something like this.

I have tried SO MANY plugins like this for YEARS, none of them worked. This one did. Have about 4,000 total comments on my blog and write about WordPress speed optimization for a living, and have disabled Gravatars for about 2 years because they take so long to load – some posts have 300+ comments. My developer came across the plugin after a ton of testing, and this is the only one that actually worked. I can’t tell you how happy I am that I can finally show people’s faces in the comments. I will be referring people to this plugin to my readers. Thank you plugin developer! Tom

I tested some other plugins and they either did not work properly (e.g. only worked for comments, but not for post authors’ gravatars) or required manual changes to the theme to work. This is the plugin that gave me best results so far. There are a few details that could be improved, namely with regard to knowing whether the plugin is really working or not, as initially we see the default avatar for almost all users. But after a while we start seeing them being replaced with the proper, locally cached, avatars. Also, I think the Apache rules set by default are not appropriate to recent Apache versions (uses Order Allow,Deny instead of Require). Even though the installation instructions mention the htaccess file, it would be useful to see a “warning” when setting up the plugin mentioning the file, as most users will likely only check instructions if they have problems with the plugin. Being aware of the htaccess file is important, as we may need to modify it (besides the permission instructions, the cache settings the plugin uses conflict with the cache setting I had in place).
