 Step 1 : Are the C# Mono 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 C# Mono program used compared to the fastest Java 6 -server program.


 Step 2 : Are the C# Mono 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 C# Mono program used compared to the fastest Java 6 -server program.

 Step 3 : Are the C# Mono 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 C# Mono program are shown for comparison against measurements of the fastest Java 6 -server program.
