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

I have been developing some perls scripts on a P1 133 linux machine with 64 megs of RAM. The application runs fine and at a good speed (pages will load in less than 3 seconds). The problem occurs when I move the code over to and embedded linux box (with the same stats), it suddenly takes close to 30 seconds to load each page.

Is this a problem related to embedded linux? Are there any opimizations I could do to speed up the loading of the modules? To be quite honest, I experience in this paticular case is pretty low, so and help at all would be great.

Cheers,
Bryan

    How do you know that it's the module loading that is taking so long? Have you profiled your program on the embedded machine?

      That's definately a good idea, but I can't profile my program on the embedded machine because it doesn't have a profile module installed (Devel::Profile) and I am unable to install it on the box. (company policies, it's pretty much a pain in the a$$)

      Basically, the way I figured it out was by writing a few test scripts and adding features to it to see when the slow down occurs. From there I narrowed it down to when I try using a module.

        Any module? Have you tried it with a very short and simple plain-Perl module? How about requiring a simple .pl file? Or is it only the more complicated modules (which might have locally-compiled binary components)? That kind of information might help further diagnose the problem...
