Hi guys,

We are now fully functional with WPML and happy with the product and its features. However, we suffer from slow loading of the pages. Therefore, we would like to get some ideas what you guys would recommend to improve it. For instance a caching plugin or a CDN plugin. However, we see some issues on the internet from people using these. What plugins or services would you recommend to implement? Your input is very, very much appreciated.

Looking forward to hearing from you, cheers,
