Are the Lua LuaJIT programs faster?
Do the Lua LuaJIT programs use optimized assembly code libraries? Are they small simple programs or very optimized programs? Do the Lua LuaJIT programs use a fraction of the time used by other programs or do they use several times more?
| Lua LuaJIT used what fraction? used how many times more? | ||||
|---|---|---|---|---|
| Programs | Time | Memory | Code | Reduced N |
| ↓ pidigits | 1/61 | 1/14 | ± | |
| ↓ fannkuch | 1/6 | 1/10 | ± | |
| ↓ k-nucleotide | 1/5 | 2× | 2× | |
| ↓ spectral-norm | 1/5 | 1/13 | ± | |
| ↓ n-body | 1/4 | 1/24 | ± | |
| ↓ reverse-complement | 1/3 | 2× | ± | |
| ↓ fasta | 1/2 | 1/19 | ± | |
| ↓ binary-trees | 2× | 5× | ± | |
± look at the measurements and then look at the programs.
