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 101.95 890,168 664 374.32 90% 93% 93% 91% Node js 19.22 1,000,628 711 61.94 80% 82% 82% 79% k-nucleotide source secs mem gz busy cpu load Lua 166.12 596,444 613 176.43 3% 79% 21% 4% Node js 26.32 397,472 1812 77.28 74% 71% 62% 87% n-body source secs mem gz busy cpu load Lua 292.55 1,224 1305 309.18 60% 22% 2% 21% Node js 26.28 35,412 1268 28.03 2% 0% 4% 100% fasta source secs mem gz busy cpu load Lua 42.29 2,736 1061 58.72 6% 11% 24% 97% Node js 3.62 67,488 2047 10.61 72% 75% 72% 74% reverse-complement source secs mem gz busy cpu load Lua 72.92 2,164,164 752 77.21 2% 4% 4% 96% Node js 4.10 1,340,368 1480 8.58 52% 56% 73% 28% mandelbrot source secs mem gz busy cpu load Lua 128.80 21,684 623 447.54 85% 90% 88% 85% Node js 6.84 88,016 1122 26.99 98% 98% 99% 98% spectral-norm source secs mem gz busy cpu load Lua 162.63 2,636 329 172.22 36% 1% 4% 65% Node js 4.40 61,768 999 16.63 93% 97% 95% 93% fannkuch-redux source secs mem gz busy cpu load Lua 833.78 1,152 462 893.00 14% 67% 21% 5% Node js 19.48 58,152 1313 77.05 99% 99% 99% 99% regex-redux source secs mem gz busy cpu load Lua Failed Node js 9.53 756,856 668 12.74 71% 24% 13% 26% pidigits source secs mem gz busy cpu load Lua Failed Node js 2.58 36,368 599 2.97 100% 6% 7% 2% Lua Lua 5.4.0 Copyright (C) 1994-2020 Lua.org, PUC-Rio Node js v14.2.0 all Lua programs & measurements all Node js programs & measurements
