 # Performance Results
 
-MFC has been extensively benchmarked on CPUs and GPU devices.
-A summary of these results follows.
+MFC has been benchmarked on several CPUs and GPU devices.
+This page shows a summary of these results.
 
 ## Expected time-steps/hour
 
-The following table outlines expected performance in terms of the number of time steps per hour (rounded to the nearest hundred, higher is better).
-A 3D inviscid, 6-equation (`'model_eqns' : 3`) problem is solved for various problem sizes (grid cells) and hardware.
