Module::Compile + B::Bytecode = Faster loading ?

cosimo has asked for the wisdom of the Perl Monks concerning the following question:

I saw B::Bytecode and tried it out a bit.
Then I saw Module::Compile and tried it out a bit.

Now I'd like to mix and match them and compile a module (*.pm) to bytecode and save the result as *.pmc

The point would be saving parsing and bytecode compiling for each program execution, given that I load hundreds of modules every time.
I suppose I am the first one coming up with this Cool Idea™, uh? ;-)
From what I read, perl already loads *.pmc files, but:

is there a ready-made solution to this problem?
is it sane to do that?
is B::Bytecode going to be abandoned?

is there a ready-made solution to this problem? Not really no. If possible, the best solution is to keep the program running all the time. (See for example, mod_perl) is it sane to do that? It's not going to be much faster (and quite possibly slower) than just compiling the modules at run-time. If you don't use all the modules all the time, you might get better results by using `require` and/or `Autoloader` to load code when you need it instead of all at once. is B::Bytecode going to be abandoned? As far as I know, yes. "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply] [d/l] [select]

You should already be able to say: `perl -MO=Bytecode,-H,-oFoo/Bar.pmc Foo/Bar.pm` [download] to compile Foo/Bar.pm to pmc. You can use that to test out whether your theories will work. -- Randal L. Schwartz, Perl hacker	[reply] [d/l]

Thanks merlyn, I don't know why, but looking at the docs, I tried with `-O2` rather than `-H` and that failed miserably... Now, I only have to bytecode-compile a hundred modules, hope that the process works for all of them, and see if that saves time or not... :-) I'll try to automate the whole thing for the most used modules.

It probably doesn't. Loading code with B::Bytecode is reported to be slower than loading code from source. ⠤⠤ ⠙⠊⠕⠞⠁⠇⠑⠧⠊	[reply]
