F# .NET Core versus OCaml 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% OCaml 21.32 255,548 1833 59.79 91% 48% 100% 42% spectral-norm source secs mem gz busy cpu load F# .NET Core 4.29 35,228 853 16.12 92% 92% 97% 94% OCaml 15.70 3,704 377 16.86 100% 3% 5% 0% fasta source secs mem gz busy cpu load F# .NET Core 1.70 138,596 1350 6.45 95% 98% 93% 93% OCaml 6.00 199,124 1189 6.32 100% 1% 1% 4% regex-redux source secs mem gz busy cpu load F# .NET Core 7.87 971,632 599 11.18 64% 37% 28% 13% OCaml 25.23 901,944 637 27.09 4% 1% 100% 3% mandelbrot source secs mem gz busy cpu load F# .NET Core 5.78 65,644 933 22.72 99% 98% 98% 98% OCaml 14.02 5,048 717 55.89 99% 100% 100% 100% binary-trees source secs mem gz busy cpu load F# .NET Core 6.28 724,124 635 22.76 91% 93% 90% 88% OCaml 9.89 152,992 751 28.64 49% 64% 98% 79% reverse-complement source secs mem gz busy cpu load F# .NET Core 2.93 1,031,696 1140 8.52 94% 45% 60% 90% OCaml 3.74 33,944 1368 8.90 62% 58% 60% 59% fannkuch-redux source secs mem gz busy cpu load F# .NET Core 16.68 35,816 1097 65.52 98% 97% 100% 98% OCaml 16.37 19,584 1004 65.39 100% 100% 100% 100% n-body source secs mem gz busy cpu load F# .NET Core 22.20 33,660 1290 23.03 0% 100% 1% 3% OCaml 21.67 1,368 1251 23.26 3% 1% 100% 4% pidigits source secs mem gz busy cpu load F# .NET Core 1.87 35,692 905 2.01 4% 2% 4% 98% OCaml 1.76 6,056 593 1.98 100% 6% 3% 4% F# .NET Core .NET Core SDK 3.1.201 Host Version: 3.1.3; Commit: 4a9f85e9f8 <ServerGarbageCollection>true <ConcurrentGarbageCollection>true OCaml The OCaml native-code compiler, version 4.10.0 all F# .NET Core programs & measurements all OCaml programs & measurements
