 Step 1 : Are the Forth GNU GForth 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 Forth GNU GForth 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 Forth GNU GForth 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 Forth GNU GForth program used compared to the fastest Zonnon Mono program.

Forth GNU GForth used what fraction? used how many times more?
Benchmark	Time	Memory	Code
nsieve	±	1/2	±
n-body	12×	1/6	±

Forth GNU GForth used what fraction? used how many times more?
Time-used	|-	|---	25%	median	75%	---|	-|
(CPU secs)	±	±	±	6×	12×	12×	12×

± read the measurements and then read the program source code.

 Step 3 : Are the Forth GNU GForth 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 Forth GNU GForth program are shown for comparison against measurements of the fastest Zonnon Mono program.

 Step 4 : Are there other Forth GNU GForth programs for these benchmarks?

Remember - those are just the fastest Forth GNU GForth and Zonnon Mono programs measured on this OS/machine. Check if there are other implementations of these benchmark programs for Forth GNU GForth.

Maybe one of those other Forth GNU GForth programs is fastest on a different OS/machine.

 Step 5 : Are there other faster programs for these benchmarks?

Remember - those are just the fastest Forth GNU GForth and Zonnon Mono programs measured on this OS/machine. Check if there are faster implementations of these benchmark programs for other programming languages.
