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 PHP #2 12,612 441 190.33 PHP #3 12,624 1160 230.54 PHP #4 47,808 1162 232.59 PHP 12,764 482 237.28 n-body source mem gz cpu Node js #6 41,056 1268 8.43 PHP #3 12,372 1082 66.39 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 PHP 35,208 1152 27.96 PHP #2 13,444 397 55.81 PHP #3 40,068 1210 60.02 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 PHP 12,664 449 86.95 PHP #3 140,544 875 92.75 pidigits source mem gz cpu PHP #5 13,728 399 0.92 PHP #4 13,656 389 0.93 PHP #3 13,804 504 0.95 Node js #4 45,096 481 1.14 PHP #2 14,172 545 1.46 Node js #2 72,556 397 13.11 Node js #3 72,536 424 13.22 PHP 14,912 750 329.76 regex-redux source mem gz cpu PHP 178,712 816 3.66 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 PHP #3 12,448 1062 20.99 PHP #2 12,696 1050 28.67 Node js 50,304 809 37.60 k-nucleotide source mem gz cpu Node js #3 419,748 1812 43.70 PHP #4 257,260 1079 69.91 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 PHP 1,487,780 318 9.64 PHP #3 528,172 446 11.26 PHP #2 1,784,488 281 11.31 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 PHP #3 1,561,956 428 51.64 PHP #2 748,408 423 62.27 PHP 748,424 451 62.40 PHP #4 1,558,972 779 62.76 PHP #7 1,589,184 760 64.15 PHP #5 803,212 1040 85.70 PHP #6 802,924 868 90.44 PHP PHP 8.1.5 (cli) (built: May 5 2022 10:44:00) (NTS) Copyright (c) The PHP Group Zend Engine v4.1.5, Copyright (c) Zend Technologies Node js v18.1.0 all PHP programs & measurements all Node js programs & measurements
