Step 1 : Are the Lua 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 Lua program used compared to the fastest Perl program.
Step 2 : Are the Lua 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 Lua program used compared to the fastest Perl program.
| Lua used what fraction? used how many times more? | ||||
|---|---|---|---|---|
| Benchmark | Time | Memory | Code | Reduced N |
| mandelbrot | 1/8 | 1/3 | ± | |
| fasta | 1/6 | 1/2 | ± | |
| spectral-norm | 1/6 | 1/7 | 1/3 | |
| n-body | 1/3 | 1/2 | ± | |
| binary-trees | 1/2 | 2× | ± | |
| pidigits | ± | 1/2 | ± | |
| fannkuch | ± | 1/2 | ± | |
| k-nucleotide | ± | ± | 2× | |
| reverse-complement | 4× | ± | 2× | |
± read the measurements and then read the program source code.
Step 3 : Are the Lua 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 Lua program are shown for comparison against measurements of the fastest Perl program.
