[Chiuso] Optimizing string processing

Background of the issue:
We are experiencing 504 errors when trying to update Formidable forms on our site link nascosto. After conducting a conflict test, we found that the issue is related to the Formidable Multilingual plugin. Formidable support identified that the root cause is WPML's string registration process, specifically the wpml_register_single_string function. Our site has over 90,000 translation strings, and WPML processes all of them during each form save, exceeding our server's PHP execution timeout limits. Our hosting environment has strict timeout policies, preventing us from extending PHP execution time limits.

Symptoms:
504 errors occur when updating Formidable forms due to WPML's string registration process.

Questions:
Are there any ways that we can optimize string processing for this site so we don't run into these 504 errors?
