 Step 1 : Are the Eiffel SmartEiffel programs faster? At a glance.

This chart shows 3 comparisons - Time-used, Memory-used and Code-used.

Each chart bar shows, for one unidentified benchmark, how much the fastest Eiffel SmartEiffel program used compared to the fastest C++ GNU g++ program.


 Step 2 : Are the Eiffel SmartEiffel programs faster? Approximately.

This table shows 3 comparisons - Time-used, Memory-used and Code-used.

Each table row shows, for one named benchmark, how much the fastest Eiffel SmartEiffel program used compared to the fastest C++ GNU g++ program.

 Step 3 : Are the Eiffel SmartEiffel programs faster? Measurements.

This table shows 5 measurements - CPU Time, Elapsed Time, Memory, Code and ~ CPU Load.

For each named benchmark, measurements of the fastest Eiffel SmartEiffel program are shown for comparison against measurements of the fastest C++ GNU g++ program.
