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 7.54 1,363,756 744 22.72 74% 73% 73% 82% k-nucleotide source secs mem gz busy cpu load Lua 119.24 596,500 613 119.78 0% 100% 0% 0% Node js 15.73 395,496 1812 43.40 76% 61% 94% 45% fasta source secs mem gz busy cpu load Lua 28.31 2,840 1061 28.57 0% 1% 0% 100% Node js 2.02 67,708 2047 6.24 77% 75% 83% 74% 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 1,522,216 1480 4.32 58% 60% 14% 72% mandelbrot source secs mem gz busy cpu load Lua 86.29 18,496 623 304.76 86% 88% 100% 80% Node js 4.04 89,736 1122 15.91 98% 99% 98% 98% n-body source secs mem gz busy cpu load Lua 217.77 1,288 1193 218.86 0% 0% 0% 100% Node js 8.40 34,280 1268 8.84 1% 3% 2% 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 61,216 999 6.16 83% 84% 85% 83% fannkuch-redux source secs mem gz busy cpu load Lua 719.15 1,224 462 723.72 0% 0% 0% 100% Node js 11.92 61,268 1313 45.47 95% 94% 96% 96% regex-redux source secs mem gz busy cpu load Lua Failed Node js 4.76 1,152,480 668 5.85 29% 91% 1% 1% pidigits source secs mem gz busy cpu load Lua Failed Node js 1.16 34,968 599 1.18 99% 2% 0% 1% Lua Lua 5.4.0 Copyright (C) 1994-2020 Lua.org, PUC-Rio Node js v15.0.1 all Lua programs & measurements all Node js programs & measurements
