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 Perl #3 5,064 427 1,267.96 Perl #2 12,308 570 1,626.37 Perl 5,288 457 1,731.08 n-body source mem gz cpu Node js #6 41,056 1268 8.43 Perl #2 6,280 1429 492.03 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 Perl #4 12,044 555 92.70 Perl #5 7,732 340 99.89 Perl 7,708 333 105.24 Perl #2 7,040 343 484.05 Perl #3 18,328 850 498.71 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 Perl 62,064 586 1,883.51 pidigits source mem gz cpu Node js #4 45,096 481 1.14 Perl #4 8,356 261 1.84 Perl #2 8,368 389 1.96 Perl 12,616 463 9.93 Node js #2 72,556 397 13.11 Node js #3 72,536 424 13.22 regex-redux source mem gz cpu Node js #3 1,045,556 668 5.97 Node js #4 985,940 463 6.24 Perl 205,584 464 21.87 Perl #2 204,960 710 28.74 Perl #3 157,276 854 29.80 Perl #4 157,228 820 29.95 Perl #5 Bad Output fasta source mem gz cpu Node js #5 101,844 2047 6.38 Node js 50,304 809 37.60 Perl 55,124 871 62.41 Perl #4 6,336 966 129.28 Perl #2 6,224 922 198.31 k-nucleotide source mem gz cpu Node js #3 419,748 1812 43.70 Node js #2 72,156 935 112.88 Node js 621,752 1008 115.69 Perl #2 659,704 359 131.83 Perl 1,253,716 652 146.30 Perl #4 1,069,344 476 150.18 Perl #3 1,147,148 513 184.94 reverse-complement source mem gz cpu Node js #7 1,556,168 1480 4.97 Perl #3 1,495,156 287 6.47 Node js #2 727,572 1221 16.87 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 Perl #5 1,048,472 797 209.51 Perl 599,520 395 252.39 Perl #4 2,519,768 761 274.10 Perl #3 2,200,608 648 390.15 Perl This is perl 5, version 34 subversion 0 (v5.34.0) x86_64-linux-thread-multi Node js v18.1.0 all Perl programs & measurements all Node js programs & measurements
