Go versus Python 3 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. n-body source secs mem gz busy cpu load Go 6.38 1,896 1200 6.43 0% 100% 1% 0% Python 3 567.56 8,076 1196 570.95 0% 0% 0% 100% spectral-norm source secs mem gz busy cpu load Go 1.44 2,356 548 5.71 99% 99% 99% 99% Python 3 120.99 13,424 407 479.86 99% 99% 99% 99% fannkuch-redux source secs mem gz busy cpu load Go 7.59 2,064 969 30.31 100% 100% 100% 100% Python 3 352.29 12,232 950 1,392.10 97% 99% 100% 99% mandelbrot source secs mem gz busy cpu load Go 3.75 34,832 894 14.92 100% 99% 99% 100% Python 3 163.32 12,080 688 642.00 98% 98% 98% 98% fasta source secs mem gz busy cpu load Go 1.28 11,276 1404 3.78 65% 86% 81% 65% Python 3 37.32 846,264 1947 71.03 10% 67% 83% 30% k-nucleotide source secs mem gz busy cpu load Go 8.30 160,300 1607 31.96 96% 98% 96% 95% Python 3 46.28 241,108 1967 176.42 94% 97% 95% 96% reverse-complement source secs mem gz busy cpu load Go 1.42 1,344,600 1338 2.66 57% 36% 71% 24% Python 3 7.20 1,005,184 814 10.75 20% 53% 48% 29% binary-trees source secs mem gz busy cpu load Go 12.80 385,036 1017 43.87 85% 87% 85% 86% Python 3 51.07 278,324 589 178.28 85% 86% 93% 85% pidigits source secs mem gz busy cpu load Go 1.00 8,952 683 1.04 0% 3% 99% 2% Python 3 1.28 12,024 567 1.29 0% 1% 100% 0% regex-redux source secs mem gz busy cpu load Go 3.94 323,252 810 6.14 74% 30% 19% 33% Python 3 1.36 111,852 1403 2.64 32% 40% 33% 88% Go go version go1.16 linux/amd64 Python 3 Python 3.9.2 all Go programs & measurements all Python 3 programs & measurements
