Go 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. k-nucleotide source secs mem gz busy cpu load Go 8.30 160,300 1607 31.96 96% 98% 96% 95% Node js 15.61 396,176 1812 43.89 63% 93% 42% 84% fannkuch-redux source secs mem gz busy cpu load Go 7.59 2,064 969 30.31 100% 100% 100% 100% Node js 12.01 63,672 1313 45.81 95% 97% 94% 95% fasta source secs mem gz busy cpu load Go 1.28 11,276 1404 3.78 65% 86% 81% 65% Node js 1.96 71,268 2047 6.19 84% 81% 75% 75% reverse-complement source secs mem gz busy cpu load Go 1.42 1,344,600 1338 2.66 57% 36% 71% 24% Node js 2.09 1,534,860 1480 4.40 40% 60% 75% 36% n-body source secs mem gz busy cpu load Go 6.38 1,896 1200 6.43 0% 100% 1% 0% Node js 8.58 35,736 1268 8.64 0% 0% 100% 0% spectral-norm source secs mem gz busy cpu load Go 1.44 2,356 548 5.71 99% 99% 99% 99% Node js 1.88 67,108 999 6.23 84% 84% 81% 83% pidigits source secs mem gz busy cpu load Go 1.00 8,952 683 1.04 0% 3% 99% 2% Node js 1.28 36,568 599 1.29 0% 0% 99% 2% regex-redux source secs mem gz busy cpu load Go 3.94 323,252 810 6.14 74% 30% 19% 33% Node js 4.89 1,149,928 668 5.96 1% 6% 24% 91% mandelbrot source secs mem gz busy cpu load Go 3.75 34,832 894 14.92 100% 99% 99% 100% Node js 4.04 94,720 1122 15.94 98% 100% 99% 98% binary-trees source secs mem gz busy cpu load Go 12.80 385,036 1017 43.87 85% 87% 85% 86% Node js 7.44 1,233,920 744 23.55 79% 75% 75% 87% Go go version go1.16 linux/amd64 Node js v16.0.0 all Go programs & measurements all Node js programs & measurements
