Go versus Python 3 fastest programs Always look at the source code. These are only the fastest programs. Look at the other programs. They may seem more-like a fair comparison to you. mandelbrot source secs mem gz busy cpu load Go 5.55 30,300 894 22.11 99% 99% 99% 100% Python 3 263.87 48,268 688 1,054.07 100% 100% 100% 100% n-body source secs mem gz busy cpu load Go 21.26 1,888 1310 22.28 3% 0% 100% 2% Python 3 891.12 8,416 1196 924.03 1% 53% 47% 2% spectral-norm source secs mem gz busy cpu load Go 4.12 2,704 548 15.93 96% 98% 97% 96% Python 3 170.10 49,484 417 670.83 99% 98% 98% 99% fannkuch-redux source secs mem gz busy cpu load Go 14.93 3,484 969 59.67 100% 100% 100% 100% Python 3 494.58 47,432 950 1,956.79 98% 99% 98% 100% fasta source secs mem gz busy cpu load Go 2.11 4,228 1358 5.66 69% 65% 64% 70% Python 3 63.63 841,056 1947 127.80 58% 61% 44% 37% k-nucleotide source secs mem gz busy cpu load Go 12.67 150,584 1722 47.44 95% 90% 93% 96% Python 3 72.58 183,484 1967 276.33 95% 95% 94% 97% reverse-complement source secs mem gz busy cpu load Go 3.73 826,488 611 4.10 88% 6% 2% 14% Python 3 16.41 1,772,696 434 17.57 1% 78% 28% 0% binary-trees source secs mem gz busy cpu load Go 25.19 397,116 1007 86.01 88% 86% 84% 83% Python 3 80.82 448,104 589 288.23 91% 88% 91% 86% pidigits source secs mem gz busy cpu load Go 2.04 8,724 603 2.36 20% 32% 33% 31% Python 3 2.39 12,200 567 2.55 64% 37% 5% 1% regex-redux source secs mem gz busy cpu load Go 7.21 326,552 810 10.19 22% 18% 87% 14% Python 3 2.67 111,864 1403 4.86 87% 30% 29% 35% Go go version go1.14 linux/amd64 Python 3 Python 3.8.0 all Go programs & measurements all Python 3 programs & measurements
