Node js versus Dart fastest performance 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 seconds, less gz source code. fannkuch-redux source secs mem gz cpu secs Dart #3 41.08 19,532 553 41.08 Node js #5 11.57 86,784 1320 45.93 Dart #5 12.74 19,532 1227 50.64 Dart #2 59.91 19,532 510 59.91 n-body source secs mem gz cpu secs Dart #6 7.02 19,536 1318 7.02 Node js #6 8.35 46,728 1274 8.36 Dart #2 9.43 19,536 1273 9.43 Dart #3 11.45 19,536 1413 11.45 spectral-norm source secs mem gz cpu secs Dart 5.32 19,792 468 5.32 Node js #7 5.36 45,888 420 5.36 Node js 5.37 47,360 326 5.39 Dart #6 1.51 19,800 1202 5.68 Node js #6 1.55 94,080 1002 5.92 Dart #2 3.34 23,552 1173 12.57 mandelbrot source secs mem gz cpu secs Dart #3 15.33 19,664 620 15.32 Node js #3 4.05 125,696 1128 15.99 Dart #4 4.23 72,704 988 16.59 Node js #2 28.35 53,784 422 28.38 Dart #2 29.80 19,536 494 29.80 Node js 136.10 48,576 380 136.11 Dart 183.52 19,536 462 183.51 Dart #6 Bad Output pidigits source secs mem gz cpu secs Node js #4 1.24 50,540 487 1.26 Dart #2 2.82 19,792 496 2.86 Dart #3 3.19 19,792 495 3.24 Node js #2 14.18 77,952 405 14.19 Node js #3 14.19 78,028 431 14.20 regex-redux source secs mem gz cpu secs Node js #3 4.34 790,368 675 5.44 Node js #4 5.48 975,456 471 5.65 Dart #4 15.22 520,384 513 15.28 Dart #5 10.04 520,828 710 15.51 Dart #2 19.06 557,692 667 19.46 Dart #3 10.90 572,356 1061 19.59 fasta source secs mem gz cpu secs Dart #4 3.95 404,164 1307 4.05 Dart 4.43 19,532 1407 4.44 Dart #5 2.92 410,268 1489 4.67 Dart #3 4.87 491,188 1114 4.88 Node js #5 2.21 100,552 2050 6.20 Dart #2 14.48 19,532 1075 14.48 Node js 40.47 50,244 815 40.80 k-nucleotide source secs mem gz cpu secs Node js #3 15.38 422,240 1817 41.85 Dart #3 19.89 221,660 1526 59.29 Node js #2 37.49 479,968 941 112.46 Node js 39.64 335,272 1011 115.24 Dart 554.27 464,520 628 554.53 reverse-complement source secs mem gz cpu secs Dart #5 9.27 1,994,704 942 12.38 Node js #2 15.89 717,660 1228 16.53 Dart 18.00 1,001,052 651 18.86 Dart #3 60.93 6,340,156 571 62.93 Dart #2 100.97 6,336,040 575 104.01 Node js #7 Bad Output Dart #4 Bad Output binary-trees source secs mem gz cpu secs Dart #6 11.41 448,748 488 15.23 Dart #7 10.15 709,208 869 22.93 Dart #4 10.21 698,844 1394 23.46 Dart #5 12.28 523,328 1023 28.28 Node js #7 18.49 1,291,392 458 30.94 Node js #6 9.59 1,275,572 752 32.36 Node js 9.68 1,230,804 717 35.09 Dart #3 15.90 1,236,508 1219 39.62 Node js v21.7.3 Dart Dart SDK version: 3.3.0 (stable) Tue Feb 13 10:25:19 2024 all Node js programs & measurements all Dart programs & measurements
