Lua versus Node js fastest programs Always look at the source code. These are only the fastest programs. Look at the other programs. They may seem more-like a fair comparison to you. binary-trees source secs mem gz busy cpu load Lua 50.85 884,352 664 189.06 92% 97% 91% 92% Node js 7.34 1,262,364 744 22.41 75% 84% 72% 75% k-nucleotide source secs mem gz busy cpu load Lua 119.24 596,500 613 119.78 0% 100% 0% 0% Node js 15.48 395,304 1812 42.72 77% 92% 61% 46% fasta source secs mem gz busy cpu load Lua 28.31 2,840 1061 28.57 0% 1% 0% 100% Node js 2.02 67,936 2047 6.27 78% 81% 75% 75% reverse-complement source secs mem gz busy cpu load Lua 44.41 2,165,032 752 44.52 0% 0% 100% 0% Node js 2.12 1,525,056 1481 4.38 48% 27% 70% 62% mandelbrot source secs mem gz busy cpu load Lua 86.29 18,496 623 304.76 86% 88% 100% 80% Node js 4.03 89,888 1122 15.89 99% 98% 98% 99% n-body source secs mem gz busy cpu load Lua 217.77 1,288 1193 218.86 0% 0% 0% 100% Node js 8.36 34,332 1268 8.37 0% 0% 0% 100% spectral-norm source secs mem gz busy cpu load Lua 87.25 2,736 329 87.59 0% 0% 100% 0% Node js 1.84 61,080 999 6.15 84% 81% 86% 83% fannkuch-redux source secs mem gz busy cpu load Lua 719.15 1,224 462 723.72 0% 0% 0% 100% Node js 11.89 61,216 1313 45.33 96% 94% 96% 94% regex-redux source secs mem gz busy cpu load Lua Failed Node js 4.76 1,152,392 668 5.82 1% 1% 28% 91% pidigits source secs mem gz busy cpu load Lua Failed Node js 1.16 34,980 599 1.21 1% 1% 99% 3% Lua Lua 5.4.0 Copyright (C) 1994-2020 Lua.org, PUC-Rio Node js v15.2.1 all Lua programs & measurements all Node js programs & measurements
