Anonymous  is this an imported model?   or are you connecting directly to a data source.   I would check the memory on your computer to see if this is affecting it.  If you give more information about how you are doing this that woud be helpful

      Theres about 70 tables in the model its on top of a data warehouse basically

      Lots of DAX measures...

      The model has gone through a number of iterations and restructuring/renaming

      It just seems it takes a long time/is slow when making/applying changes, also in creatign new DAX measures also

      Very annnoying as basically data modelling is an iterative process with additions/changes continually made and with this poor perfromance issue takes a long time
