F# .NET Core versus Haskell GHC 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. k-nucleotide source secs mem gz busy cpu load F# .NET Core 5.80 183,360 1907 19.47 86% 66% 88% 96% Haskell GHC 36.99 639,092 1486 130.13 89% 87% 88% 88% reverse-complement source secs mem gz busy cpu load F# .NET Core 2.93 1,031,696 1140 8.52 94% 45% 60% 90% Haskell GHC 6.59 501,560 1020 9.74 92% 15% 19% 22% binary-trees source secs mem gz busy cpu load F# .NET Core 6.28 724,124 635 22.76 91% 93% 90% 88% Haskell GHC 13.41 450,148 592 49.72 93% 92% 96% 90% fannkuch-redux source secs mem gz busy cpu load F# .NET Core 16.68 35,816 1097 65.52 98% 97% 100% 98% Haskell GHC 18.64 4,392 842 73.68 97% 99% 99% 100% n-body source secs mem gz busy cpu load F# .NET Core 22.20 33,660 1290 23.03 0% 100% 1% 3% Haskell GHC 21.87 4,388 1883 86.43 98% 100% 98% 99% spectral-norm source secs mem gz busy cpu load F# .NET Core 4.29 35,228 853 16.12 92% 92% 97% 94% Haskell GHC 4.09 4,184 987 16.03 98% 99% 99% 97% pidigits source secs mem gz busy cpu load F# .NET Core 1.87 35,692 905 2.01 4% 2% 4% 98% Haskell GHC 1.76 6,516 1694 1.79 0% 1% 1% 99% mandelbrot source secs mem gz busy cpu load F# .NET Core 5.78 65,644 933 22.72 99% 98% 98% 98% Haskell GHC 5.06 37,660 1975 20.09 98% 100% 100% 100% fasta source secs mem gz busy cpu load F# .NET Core 1.70 138,596 1350 6.45 95% 98% 93% 93% Haskell GHC 1.40 8,020 1882 4.16 74% 74% 74% 75% regex-redux source secs mem gz busy cpu load F# .NET Core 7.87 971,632 599 11.18 64% 37% 28% 13% Haskell GHC 1.68 308,212 2213 3.92 46% 77% 44% 66% F# .NET Core .NET Core SDK 3.1.201 Host Version: 3.1.3; Commit: 4a9f85e9f8 <ServerGarbageCollection>true <ConcurrentGarbageCollection>true Haskell GHC The Glorious Glasgow Haskell Compilation System, version 8.8.1 all F# .NET Core programs & measurements all Haskell GHC programs & measurements
