Step 1 : Are the Prolog SWI 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 Prolog SWI program used compared to the fastest Zonnon Mono program.
Look at speed another way - look at a box plot of Time-used data.
Step 2 : Are the Prolog SWI 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 Prolog SWI program used compared to the fastest Zonnon Mono program.

± read the measurements and then read the program source code.
Step 3 : Are the Prolog SWI 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 Prolog SWI program are shown for comparison against measurements of the fastest Zonnon Mono program.
| Program Source Code | CPU secs | Elapsed secs | Memory KB | Code B | ≈ CPU Load |

Step 4 : Are there other Prolog SWI programs for these benchmarks?
Remember - those are just the fastest Prolog SWI and Zonnon Mono programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for Prolog SWI.
Maybe one of those other Prolog SWI programs is fastest on a different OS/machine.
Step 5 : Are there other faster programs for these benchmarks?
Remember - those are just the fastest Prolog SWI and Zonnon Mono 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.
