[Resolved] Wpml has been very very slow lately in back end

Problem:
If you're experiencing very slow backend performance with WPML when updating products, taking up to 20 seconds, we have investigated this issue.

Solution:
First, check your database's

_options

table for any unusually large entries that could be affecting performance. You can use the following SQL query to identify large autoloaded options:

SELECT option_id, option_name, sum(char_length(`option_value`))/1024 as size FROM `wp2x_options` WHERE `autoload` = 'yes' GROUP BY option_id ORDER BY size DESC

Next, we recommend updating to the latest version of WooCommerce Multilingual, which includes a performance upgrade. You can download it from our site here: https://wpml.org/downloads/
For more information about the performance upgrade, please visit: https://wpml.org/compatibility/2023/11/woocommerce-multilingual-5-3-full-support-for-hpos-and-more/
After updating, go to WooCommerce -> Settings and enable HPOS. Then, test your site's performance again.

If you have tested and the issue persists, or if this solution doesn't seem relevant to your situation, please open a new support ticket with us for further assistance: Contact WPML Support
