F# .NET 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. regex-redux source secs mem gz busy cpu load F# .NET 2.85 1,301,192 611 7.36 51% 92% 59% 56% OCaml 14.84 901,904 637 15.29 100% 0% 1% 1% k-nucleotide source secs mem gz busy cpu load F# .NET 3.65 184,680 1907 12.58 94% 84% 85% 83% OCaml 14.87 255,560 1833 40.68 48% 50% 86% 90% spectral-norm source secs mem gz busy cpu load F# .NET 1.55 31,916 853 5.83 92% 98% 93% 93% OCaml 5.36 3,436 377 5.37 0% 0% 100% 0% fasta source secs mem gz busy cpu load F# .NET 1.14 120,528 1350 4.18 94% 94% 89% 91% OCaml 3.27 203,380 1189 3.31 1% 0% 0% 100% mandelbrot source secs mem gz busy cpu load F# .NET 3.77 64,912 933 14.73 99% 97% 98% 97% OCaml 7.56 4,620 717 30.12 100% 100% 99% 100% binary-trees source secs mem gz busy cpu load F# .NET 2.73 719,880 635 9.33 80% 89% 87% 85% OCaml 4.04 152,736 751 11.19 39% 77% 68% 93% reverse-complement source secs mem gz busy cpu load F# .NET 1.51 1,030,852 1140 4.19 93% 36% 58% 91% OCaml 1.66 34,044 1368 4.25 61% 65% 61% 69% fannkuch-redux source secs mem gz busy cpu load F# .NET 8.65 31,784 1097 33.57 98% 99% 94% 98% OCaml 8.52 19,072 1004 34.08 100% 100% 100% 100% n-body source secs mem gz busy cpu load F# .NET 6.88 34,744 1617 6.92 0% 100% 1% 0% OCaml 6.72 1,464 1251 6.76 0% 100% 0% 1% pidigits source secs mem gz busy cpu load F# .NET 0.82 34,428 905 0.83 1% 2% 96% 1% OCaml 0.74 6,144 593 0.78 0% 0% 100% 4% F# .NET .NET SDK 5.0.100 Host Version: 5.0.0; Commit: cf258a14b7 <ServerGarbageCollection>true OCaml The OCaml native-code compiler, version 4.11.0 all F# .NET programs & measurements all OCaml programs & measurements
