Step 1 : Are the Racket programs faster? At a glance.
This chart shows 3 comparisons - Time-used, Memory-used and Code-used ~ speed and size.
Each chart bar shows, for one unidentified benchmark, how much the fastest Racket program used compared to the fastest Java 7 -server program.
Look at speed another way - look at a box plot of Time-used data.
Step 2 : Are the Racket programs faster? Approximately.
This table shows 3 comparisons - Time-used, Memory-used and Code-used ~ speed and size.
Each table row shows, for one named benchmark, how much the fastest Racket program used compared to the fastest Java 7 -server program.

Step 3 : Are the Racket programs faster? Measurements.
This table shows 5 measurements - CPU Time, Elapsed Time, Memory, Code and ≈ CPU Load ~ speed and size.
For each named benchmark, measurements of the fastest Racket program are shown for comparison against measurements of the fastest Java 7 -server program.

Step 4 : Are there other Racket programs for these benchmarks?
Remember - those are just the fastest Racket and Java 7 -server programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for Racket.
Maybe one of those other Racket programs is fastest on a different OS/machine.
Step 5 : Are there other faster programs for these benchmarks?
Remember - those are just the fastest Racket and Java 7 -server programs measured on this OS/machine. Check if there are faster implementations of these benchmark programs for other programming languages.
Maybe one of those other programs is fastest on a different OS/machine.
