I tried all the suggested actions and it didn't help. The only thing which helped (on to top of using Efficiency Mode) was to disable Hyperthreading. That reduced the issue pretty much but did not remove it completely.

    can you attached your design.qar here for the duplication of issue? If you need to privately send us the design, let us know.

        Hi,

        I am trying to attach the design.qar file but it seems like it's not woking (maybe file is too big, 38MB?). How can I send it to you? And do you also need the database?
