They may seem more-like a fair comparison to you. pidigits source secs mem gz busy cpu load Go 2.10 8,448 603 2.17 1% 48% 55% 0% Rust 1.75 3,060 1366 1.83 2% 2% 100% 1% fasta source secs mem gz busy cpu load Go 2.08 3,560 1358 5.61 80% 37% 76% 78% Rust 1.51 2,036 1906 4.59 74% 74% 82% 74% fannkuch-redux source secs mem gz busy cpu load Go 14.79 1,532 969 58.94 100% 100% 100% 100% Rust 10.42 876 1016 40.80 100% 93% 99% 99% spectral-norm source secs mem gz busy cpu load Go 3.96 2,752 548 15.74 99% 99% 99% 99% Rust 1.97 2,220 1126 7.88 100% 99% 99% 100% reverse-complement source secs mem gz busy cpu load Go 3.83 1,782,940 1338 6.67 21% 74% 16% 62% Rust 1.69 994,656 1330 2.96 25% 25% 46% 79% k-nucleotide source secs mem gz busy cpu load Go 11.77 160,184 1607 44.52 94% 98% 94% 92% Rust 5.17 135,372 1841 15.76 80% 100% 56% 69% regex-redux source secs mem gz busy cpu load Go 6.84 340,376 810 9.43 30% 43% 13% 52% Rust 2.13 153,508 986 3.18 84% 34% 15% 16% mandelbrot source secs mem gz busy cpu load Go 5.47 31,088 905 21.77 100% 99% 99% 99% Rust 1.70 32,308 1332 6.69 98% 98% 99% 98% n-body source secs mem gz busy cpu load Go 21.25 1,588 1310 21.82 2% 0% 100% 1% Rust 6.07 876 1753 6.18 0% 1% 100% 0% binary-trees source secs mem gz busy cpu load Go 26.46 572,836 1007 89.76 86% 84% 85% 85% Rust 3.32 199,724 721 12.07 88% 88% 87% 100% Go go version go1.13 linux/amd64 Rust rustc 1.41.0 (5e1a79984 2020-01-27) LLVM version: 9.0 all Go programs & measurements all Rust programs & measurements
