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 1.20 200,160 721 4.27 87% 86% 86% 98% Go 12.57 352,428 1017 43.46 89% 87% 85% 85% mandelbrot source secs mem gz busy cpu load Rust 0.92 26,112 757 3.67 100% 100% 100% 100% Go 3.75 33,820 905 14.95 100% 100% 100% 100% k-nucleotide source secs mem gz busy cpu load Rust 2.64 131,408 1578 8.41 66% 86% 92% 75% Go 8.16 150,376 1722 31.09 97% 97% 96% 91% regex-redux source secs mem gz busy cpu load Rust 1.30 153,228 986 1.82 12% 85% 28% 15% Go 3.55 375,092 810 5.86 30% 46% 21% 68% spectral-norm source secs mem gz busy cpu load Rust 0.72 2,448 817 2.84 100% 99% 100% 99% Go 1.44 2,340 548 5.69 99% 99% 99% 99% reverse-complement source secs mem gz busy cpu load Rust 0.74 994,912 1330 1.34 27% 81% 46% 27% Go 1.43 1,467,692 1338 2.74 63% 42% 40% 47% n-body source secs mem gz busy cpu load Rust 3.42 1,844 1753 3.44 100% 0% 0% 0% Go 6.38 1,768 1200 6.38 0% 0% 0% 100% pidigits source secs mem gz busy cpu load Rust 0.88 2,904 1420 0.90 0% 100% 2% 0% Go 1.25 9,120 603 1.24 0% 48% 0% 51% fasta source secs mem gz busy cpu load Rust 0.94 2,180 1961 3.12 81% 81% 81% 89% Go 1.20 10,852 1404 3.64 79% 71% 74% 79% fannkuch-redux source secs mem gz busy cpu load Rust 7.54 1,012 1016 29.62 95% 98% 100% 100% Go 8.28 2,432 969 33.06 100% 100% 100% 100% Rust rustc 1.46.0 (04488afe3 2020-08-24) LLVM version: 9.0 Go go version go1.15.2 linux/amd64 all Rust programs & measurements all Go programs & measurements
