Rust versus Go 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. binary-trees source secs mem gz busy cpu load Rust 1.30 111,692 721 4.69 99% 86% 86% 88% Go 12.36 396,032 1007 43.05 88% 86% 89% 85% mandelbrot source secs mem gz busy cpu load Rust 0.94 26,316 719 3.71 99% 98% 100% 98% Go 3.73 28,764 905 14.88 100% 99% 99% 100% k-nucleotide source secs mem gz busy cpu load Rust 2.76 132,424 1578 9.03 69% 100% 67% 91% Go 8.03 150,544 1722 30.53 97% 96% 95% 92% regex-redux source secs mem gz busy cpu load Rust 1.28 153,836 986 1.79 13% 83% 13% 31% Go 3.57 382,828 810 5.71 21% 42% 47% 51% spectral-norm source secs mem gz busy cpu load Rust 0.71 2,436 1126 2.86 100% 100% 100% 100% Go 1.43 2,668 548 5.70 99% 99% 99% 100% n-body source secs mem gz busy cpu load Rust 3.33 688 1753 3.42 0% 100% 2% 1% Go 6.34 1,792 1200 6.44 1% 100% 0% 0% reverse-complement source secs mem gz busy cpu load Rust 0.74 994,956 1330 1.36 47% 59% 49% 28% Go 1.38 1,465,376 1338 2.54 51% 47% 38% 50% pidigits source secs mem gz busy cpu load Rust 0.88 2,884 1306 0.89 1% 0% 0% 100% Go 1.23 8,580 603 1.26 1% 50% 2% 50% fasta source secs mem gz busy cpu load Rust 0.93 2,180 1906 3.08 80% 89% 81% 81% Go 1.20 11,452 1404 3.62 73% 70% 84% 74% fannkuch-redux source secs mem gz busy cpu load Rust 6.87 1,016 1016 26.97 100% 99% 94% 100% Go 8.51 2,732 969 34.00 100% 100% 100% 100% Rust rustc 1.44.1 (c7087fe00 2020-06-17) LLVM version: 9.0 Go go version go1.14.4 linux/amd64 all Rust programs & measurements all Go programs & measurements
