They may seem more-like a fair comparison to you. pidigits source secs mem gz busy cpu load Go 2.04 8,724 603 2.36 20% 32% 33% 31% Rust 1.75 2,984 1420 1.83 0% 2% 3% 100% fannkuch-redux source secs mem gz busy cpu load Go 14.93 3,484 969 59.67 100% 100% 100% 100% Rust 11.06 1,020 1016 43.39 100% 99% 100% 93% fasta source secs mem gz busy cpu load Go 2.11 4,228 1358 5.66 69% 65% 64% 70% Rust 1.51 2,172 1961 4.77 76% 86% 77% 77% spectral-norm source secs mem gz busy cpu load Go 4.12 2,704 548 15.93 96% 98% 97% 96% Rust 1.99 2,428 1126 7.91 99% 100% 99% 99% reverse-complement source secs mem gz busy cpu load Go 3.73 826,488 611 4.10 88% 6% 2% 14% Rust 1.68 994,920 1330 2.91 46% 79% 24% 25% k-nucleotide source secs mem gz busy cpu load Go 12.67 150,584 1722 47.44 95% 90% 93% 96% Rust 5.58 134,504 1841 16.64 73% 93% 57% 76% regex-redux source secs mem gz busy cpu load Go 7.21 326,552 810 10.19 22% 18% 87% 14% Rust 2.23 153,800 986 3.28 14% 16% 85% 32% mandelbrot source secs mem gz busy cpu load Go 5.55 30,300 894 22.11 99% 99% 99% 100% Rust 1.71 32,704 1332 6.73 98% 98% 98% 100% n-body source secs mem gz busy cpu load Go 21.26 1,888 1310 22.28 3% 0% 100% 2% Rust 5.98 688 1753 6.01 0% 0% 100% 1% binary-trees source secs mem gz busy cpu load Go 25.19 397,116 1007 86.01 88% 86% 84% 83% Rust 3.30 174,904 721 11.87 87% 88% 87% 99% Go go version go1.14 linux/amd64 Rust rustc 1.43.0 (4fb7144ed 2020-04-20) LLVM version: 9.0 all Go programs & measurements all Rust programs & measurements
