VW Smalltalk versus Node js fastest programs Always look at the source code. These are only the fastest programs. Do some of them use manually vectorized SIMD? Look at the other programs. They may seem more-like a fair comparison to you. pidigits source secs mem gz busy cpu load VW Smalltalk 8.02 55,592 753 8.04 0% 100% 0% 0% Node js 6.14 66,508 530 6.25 1% 0% 77% 24% binary-trees source secs mem gz busy cpu load VW Smalltalk 16.33 375,880 930 37.41 70% 46% 70% 43% Node js 6.95 1,309,892 744 21.41 76% 75% 88% 69% spectral-norm source secs mem gz busy cpu load VW Smalltalk 20.54 248,124 1047 62.47 72% 73% 75% 84% Node js 1.84 64,452 999 6.18 83% 86% 83% 83% n-body source secs mem gz busy cpu load VW Smalltalk 108.63 55,036 1782 109.07 0% 0% 100% 0% Node js 8.39 35,548 1268 8.74 0% 2% 2% 100% fasta source secs mem gz busy cpu load VW Smalltalk 29.30 55,024 1539 29.55 0% 1% 100% 0% Node js 2.04 71,304 2047 6.32 75% 80% 80% 75% mandelbrot source secs mem gz busy cpu load VW Smalltalk 102.47 177,424 929 351.82 85% 93% 88% 77% Node js 4.04 92,960 1122 15.95 100% 98% 98% 98% k-nucleotide source secs mem gz busy cpu load VW Smalltalk 429.36 385,208 1317 432.38 0% 67% 34% 0% Node js 15.73 392,924 1812 43.25 91% 62% 75% 47% fannkuch-redux source secs mem gz busy cpu load VW Smalltalk 452.53 54,936 916 456.54 0% 0% 0% 100% Node js 11.97 63,036 1313 45.89 96% 96% 95% 96% reverse-complement source secs mem gz busy cpu load VW Smalltalk Bad Output Node js 2.13 1,525,096 1481 4.31 11% 70% 62% 60% regex-redux source secs mem gz busy cpu load No program contribute your program Node js 4.79 1,159,940 668 5.86 91% 2% 1% 29% VW Smalltalk VisualWorks® 8.3 Aug 19 2017 Node js v15.10.0 all VW Smalltalk programs & measurements all Node js programs & measurements
