Hi, I got a very slow checkout saving order for clients on my woocommerce website. Also the admin work with saving and editing products is superslow too. Without WPML the shop works fine, like before. I tried the optimizations recommended by WPML but no improvements noticed, incl. W3 Total Cache settings.

What can I do?

Hello there,

Thank you for contacting WPML support. I'd be happy to assist you further on this issue.

Performance issues depend upon the site, it's server, plugins used and furthermore, I agree that multilingual plugins take more resources than other plugins as it needs to connect all plugins/themes strings and translate them accordingly. So, the fact is that if you have more plugins and themes (with a large number of strings) WPML will try to translate them which adds significant load and you will feel the performance issue, which is normal somehow.

In every update, we are trying to increase the performances of our plugins.

Some themes and plugins can also have very slow interaction with multilingual sites. For example, if a theme/plugin loads thousands of strings (that it doesn't really need), WPML will try to translate them which adds significant load and you will feel the performance issue, in order to check if this is something coming from plugins or themes, could you please test the performance when:
- All non WPML Plugins are disabled.
- Theme is set to a WordPress default like Twenty sixteen.

This test will let us know if it's just the plugins/themes resources that are making site performance high or it's something that's in our plugin itself.

Further, here are a few things you can try to increase the site performance:

You should also enable a plugin called 'Debug Queries' and show us the DB queries that your site is generating, with and without WPML's String Translation.

Look forward to your reply.
