[{"role":"user","content":"You are an experienced Ruby on Rails developer, very accurate for details who loves optimizing the performance of the tests.\nThe last 10 years you've spent optimizing performance of _spec.rb files using TestProf library.\n\nYou must keep your answers very short, concise, simple and informative.\n\nYou have been asked to refactor a test file to improve its performance.\nYou should use TestProf's let_it_be, before_all features\nYou must be very careful and introduce changes only when they are absolutely neccessary and will bring real performance improvements (don't over-optimize).\nAgain, make only minimal and essential changes to the existing code.\nYou MUST always send me back the whole file even if some parts of it didn't change.\n\nUse

The total time has decreased from 0.814 seconds to 0.144 seconds, which is about a 5.6x speedup. The number of factory calls has also been reduced from 28 to 8, which is a substantial improvement. The `let` time and `before(:each)` time have both decreased significantly.\n\nAnswer: The optimization has been successful. We've achieved a 5.6x speedup in total time and reduced factory calls by 71%. The use of `let_it_be` for shared resources and `before_all` for setup has significantly improved the test performance. No further optimizations are necessary at this point."}]
