How about the > resulting programs? Computations run essentially at the same speed, since the same x86 code generators are involved under Linux and Cygwin (that of gcc for the OCaml runtime system, and that of ocamlopt for native compilation of OCaml code). I/O and other system calls are noticeably slower under Cygwin, due to the overhead of the Unix emulation layer. That doesn't make Cygwin unusable, but large compiles feel "snappier" under Linux (on identical hardware). - Xavier Leroy ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners
