Because WPML creates posts and pages for each language, comments from one do not appear on the other. 
This plugin merges comments from all WPML translations of the posts and pages, so that they all are displayed on each other. 
Comments are internally still attached to the post or page they were made on.
It uses the <code>get_comments()</code> api call, which in some circumstances might not return all posts.

<h3>Disclaimer about WordPress 6.5</h3>
Attention: most functionality of this plugin has been merged into WordPress 6.5! You might not need it anymore.
However, this plugin is still relevant for cases where language packs are not downloaded from WordPress.org but somewhere else, for example if you are developing your own plugins or using commercial plugins.
The Performant Translations plugin converts the translation files of those plugins to the new file format introduced in WordPress 6.5, to really optimize them for speed.
<h3>What this plugin does</h3>
This project uses a new approach to handle translation files in WordPress, making localization blazing fast.
An <a href="https://make.wordpress.org/core/2023/07/24/i18n-performance-analysis/" rel="nofollow ugc">in-depth i18n performance analysis</a> showed that localized WordPress sites load significantly slower than a site without translations.
With this plugin’s new approach to localization, this overhead is massively reduced, making your site fast again. It does so by converting <code>.mo</code> translation files to <code>.php</code> files.
If your site is using a language other than English (US), you should see immediate speed improvements simply by activating this plugin.

Performant Translations


This is a commendable effort, and it came out at the perfect time, at least for me.



I am looking forward to seeing how it evolves, and I hope to see it merged with the core in the fourth phase of the Gutenberg project.


Commendable effort


Installed this plugin to see what the effect is on my site. I am not yet 100% sure that it makes a big difference. But that all depends on the amount of texts used on your site. So far no bad experiences


Plugin speeds up the presentation of your site


This problem has been around for a long time and I've used various plugins. I hope it will be added to the core soon!


Required for non-English speaking WPs


I've got a multi language site (with WPML) that has a huge performance problem. I was not able to figure out what is actually causing the performance problem, the main problem probably has nothing to do with i18n, this plugin still helps cause it significantely speeds up the translations, leaving the only bottleneck to be the unknown problem.



Many thanks for your efforts!


Cool
