Thanks to Jeff Hanson for the following post!
With each development cycle the Revit team works to develop new features, enhance or expand existing functionality, and improve the overall performance of Revit. The 2015 development cycle was no different in this respect and overall performance of Revit 2015 has increased when tested against Revit 2014.
Of particular note is the performance of graphics related operations. In our tests we saw the greatest improvements in raster image operations (move, cop, array, etc…), view navigation, and element selection.
This year’s Revit development also included a project that alters the internal family data structure which optimizes some computation heavy update operations that are triggered when the model is changed. In some cases we have seen performance in these areas improved up to 30%.
Because of the calculation intensive nature of Revit MEP, separate performance statistics are kept for MEP functions and MEP heavy project files. The performance increases for MEP were found to be similar. MEP specific performance tests also showed increase in performance in most areas from 2014 to 2015.
You can of course test and rate the performance of Revit on your hardware and using your projects to see if you get similar results as our tests. Revit Forum has its own bench mark test. You can find more information on how to run your own test in this thread.
Give Revit 2015 performance a test of your own and let us know what you find!
