RE: Is it possible to 'precompile' a module in one luaState and quicklymove it over to another? (keywords multiple interpreters, precompile)

["Peter Pimley" <Peter.Pimley@...>]

Hi,

In the next few days I'm going to be in a similar situation.

It would be interesting to measure how much of that 0.5s is taken
actually opening the file.  That's not including reading from it, and
not including the work of interpreting it.  It might surprise you.  Are
you on a platform where file opening or seeking time is a problem?  If
you happen to be using cygwin, I think opening a file is quite a bit
more expensive than the native call.

You could test this by making the module contain no code whatsoever (but
still be a file on disk) and carrying out your timing again.

If that is where your bottleneck lies then you could hold the module in
memory in your C application (i.e. as a const char *).  Then tweak the
"require" code to look there as well.  I forget exactly how it's done,
but I'm sure it's possible.
