Do you use Java for regular development? It is a pain, the reason is 1. Slow, slow 2. Big, big and the reason that Java gets away with it, is the JIT-compiler. That mean that after enormous start-time, the program might achieve resonable performance after a couple of minutes. However, at that time, it still needs 10-20 extra megs, since the compiler is still loaded into memory. The beatty of Ocaml are the fast compilers, the optimizing compiler is faster than javac, which only produces bytecode. It is sad that so few other programming language developers realizes that the speed of the development environment matters. The only thing Ocaml can learn from Java is its libraries. If I would invent a programming language with a library today, I would just copy Java's interface. Libraries are much harder to learn than programming languages, thus standards are needed. /mattias -----Original Message----- From: Pierre.Weis@inria.fr [mailto:Pierre.Weis@inria.fr]On Behalf Of Markus Mottl Sent: Tuesday, January 02, 2001 5:08 PM To: OCAML Subject: JIT-compilation for OCaml? Hello, one thing I just wondered about is whether there are any intentions concerning a JIT-compiler for OCaml byte code similar to what Java offers. This would allow much faster execution while still retaining full portability of the byte code. Is this a goody we might expect in the (near? far?) future? - Markus Mottl -- Markus Mottl, mottl@miss.wu-wien.ac.at, http://miss.wu-wien.ac.at/~mottl
