Slow down any website dramatically

Have you created a support ticket about this problem?

Sometimes similar situations have been solved by changing a configuration setting or by addressing a compatibility issue with another plugin installed.

I suggest that you create a ticket on the WPML support forum and we’d be glad to assist.

Yes I did. The problem has resolved, but not too much. Performance issue still problematic with plugin.
I hope you can address this issue in the next release.
As I wrote before

I installed this plugin in like 30 websites and I know what I am talking about.

I changed my feedback to 4 stars.

Kind regards
