They may seem more-like a fair comparison to you. binary-trees source secs mem gz busy cpu load Rust 3.31 199,852 721 12.01 88% 88% 87% 100% Go 26.46 572,836 1007 89.76 86% 84% 85% 85% n-body source secs mem gz busy cpu load Rust 6.07 940 1753 6.16 100% 1% 0% 0% Go 21.25 1,588 1310 21.82 2% 0% 100% 1% mandelbrot source secs mem gz busy cpu load Rust 1.70 30,544 1332 6.69 98% 98% 99% 98% Go 5.47 31,088 905 21.77 100% 99% 99% 99% regex-redux source secs mem gz busy cpu load Rust 2.12 153,104 986 3.14 17% 14% 33% 84% Go 6.84 340,376 810 9.43 30% 43% 13% 52% reverse-complement source secs mem gz busy cpu load Rust 1.69 994,564 1330 2.98 45% 26% 47% 59% Go 3.83 1,782,940 1338 6.67 21% 74% 16% 62% k-nucleotide source secs mem gz busy cpu load Rust 5.38 135,192 1749 17.05 64% 73% 89% 91% Go 11.77 160,184 1607 44.52 94% 98% 94% 92% spectral-norm source secs mem gz busy cpu load Rust 1.98 2,244 1126 7.89 99% 100% 99% 99% Go 3.96 2,752 548 15.74 99% 99% 99% 99% fasta source secs mem gz busy cpu load Rust 1.51 2,044 1906 4.60 74% 73% 82% 75% Go 2.08 3,560 1358 5.61 80% 37% 76% 78% fannkuch-redux source secs mem gz busy cpu load Rust 11.08 944 1016 43.52 100% 94% 100% 99% Go 14.79 1,532 969 58.94 100% 100% 100% 100% pidigits source secs mem gz busy cpu load Rust 1.75 3,036 1366 1.77 100% 0% 1% 1% Go 2.10 8,448 603 2.17 1% 48% 55% 0% Rust rustc 1.40.0 (73528e339 2019-12-16) LLVM version: 9.0 Go go version go1.13 linux/amd64 all Rust programs & measurements all Go programs & measurements
