Background of the issue:
I am trying to optimize the performance of our Pro Carbon Racing website. Our hosting company identified that WPML string translation is consuming a lot of RAM and CPU. They suggested that the use of the similar_text() function is causing high resource usage. They recommended contacting the WPML team for a performance patch, settings to disable slug translation checks, or alternative methods. The issue can be seen at: hidden link

Symptoms:
High CPU and memory usage due to WPML string translation, specifically related to the similar_text() function.

Questions:
Is there a performance patch or update available for WPML string translation?
Are there settings to disable the specific slug translation check?
What alternative methods are available that are less resource-intensive?

Hi there,

Please update WPML to it's latest version (currently 4.8.5) which indluded some performance fixes and let me know your results, please.

I can see that you are using Advanced Custom Fields, if you go to WPML->Settings->Custom Post Types, do you see a large ammount of CPTs that are custom to your site?

The performance issue you are sharing with me reminds me of an older ticket that had a similar performance issue due to a large ammount of CPTs created/available.
