Fastest cpu secs Lua versus Node js Always look at the source code. If the fastest programs are hand-written vector instructions, does the host language matter? You might be more interested in the less optimised programs — more cpu seconds, less gz source code. fannkuch-redux source mem gz cpu Node js #5 85,336 1313 44.58 Lua 1,420 462 700.03 n-body source mem gz cpu Node js #6 41,056 1268 8.43 Lua #4 1,404 1305 228.33 Lua #2 1,476 1193 231.51 Lua 1,416 1201 249.47 spectral-norm source mem gz cpu Node js #7 41,524 414 5.38 Node js 41,668 319 5.45 Node js #6 90,932 999 6.20 Lua 2,832 329 80.47 mandelbrot source mem gz cpu Node js #3 118,180 1122 16.00 Node js #2 48,484 416 28.21 Node js 43,580 373 65.26 Lua #3 2,696 358 248.45 Lua 2,656 359 248.49 Lua #2 1,440 367 277.92 Lua #6 23,188 623 295.23 pidigits source mem gz cpu Node js #4 45,096 481 1.14 Node js #2 72,556 397 13.11 Node js #3 72,536 424 13.22 Lua #5 Failed Lua #7 Failed Lua Failed regex-redux source mem gz cpu Lua 327,952 482 2.59 Node js #3 1,045,556 668 5.97 Node js #4 985,940 463 6.24 fasta source mem gz cpu Node js #5 101,844 2047 6.38 Lua #3 2,808 1061 26.72 Lua #2 2,812 1061 27.00 Node js 50,304 809 37.60 k-nucleotide source mem gz cpu Node js #3 419,748 1812 43.70 Lua #2 596,492 613 112.22 Node js #2 72,156 935 112.88 Node js 621,752 1008 115.69 reverse-complement source mem gz cpu Node js #7 1,556,168 1480 4.97 Node js #2 727,572 1221 16.87 Lua #2 2,654,764 553 41.55 Lua #5 2,163,180 719 45.44 Lua #4 1,030,160 594 53.35 binary-trees source mem gz cpu Node js #6 1,322,340 744 27.83 Node js 1,173,028 711 36.72 Node js #7 1,107,220 451 40.72 Lua #2 963,568 412 144.57 Lua #3 927,544 684 167.23 Lua #4 927,464 664 182.34 Lua Lua 5.4.4 Copyright (C) 1994-2022 Lua.org, PUC-Rio Node js v18.1.0 all Lua programs & measurements all Node js programs & measurements
