[Resolved] Speed up WPML site

Problem:
The client's WooCommerce store experienced a slowdown after installing multiple languages using WPML. The client considered removing WPML Media and untranslated strings but was unsure if these changes would significantly improve site speed.

Solution:
We advised the client not to use PHP 8.3 as it is still in beta for WordPress and could slow down the site. Instead, we recommended using PHP 8.1. We suggested monitoring the site with the Query Monitor plugin to identify slow and duplicate queries. For managing strings, we directed the client to WPML > Support > Troubleshooting to delete unused strings and provided guidance on how to delete strings from WPML -> Strings Translation, which can be read more about here.

Additionally, we found that WPML Media does not significantly impact performance unless used for translating images specifically for different languages. We also noted that the site's hosting might contribute to performance issues due to resource limitations or database call restrictions, especially with increased content from multiple languages.

If these steps do not resolve the issue or if the solution seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
