Fastest cpu secs VW Smalltalk 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 VW Smalltalk 54,996 916 454.21 n-body source mem gz cpu Node js #6 41,056 1268 8.43 VW Smalltalk 55,180 1782 110.90 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 VW Smalltalk 55,100 642 49.21 VW Smalltalk #2 246,440 1047 62.28 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 VW Smalltalk 54,944 603 323.20 VW Smalltalk #2 178,808 929 356.29 pidigits source mem gz cpu Node js #4 45,096 481 1.14 VW Smalltalk #4 55,540 753 8.30 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 fasta source mem gz cpu Node js #5 101,844 2047 6.38 VW Smalltalk 55,916 1539 30.49 Node js 50,304 809 37.60 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 VW Smalltalk #5 385,252 1317 439.66 VW Smalltalk 385,732 1110 585.75 reverse-complement source mem gz cpu Node js #7 1,556,168 1480 4.97 Node js #2 727,572 1221 16.87 VW Smalltalk Bad Output binary-trees source mem gz cpu Node js #6 1,322,340 744 27.83 Node js 1,173,028 711 36.72 VW Smalltalk 375,616 711 36.82 VW Smalltalk #3 375,908 930 38.72 Node js #7 1,107,220 451 40.72 VW Smalltalk VisualWorks® 8.3 Aug 19 2017 Node js v18.1.0 all VW Smalltalk programs & measurements all Node js programs & measurements
