Problem: The client is experiencing slow site performance and suspects that the WPML plugin is consuming a significant amount of resources. Solution: We have analyzed the site's performance and determined that the difference in mobile performance scores with WPML turned on or off is only 2-4 points. This indicates that WPML has a minimal impact on site speed. To improve the site's performance, we recommend focusing on general mobile optimization strategies. If the site's performance does not improve after these optimizations, or if this solution does not seem relevant to your situation, please open a new support ticket with us.
