My first impression is that that list is probably too long. Remember that modules use other modules. If A uses B, you just have to use A to get both of them. There are many modules that are loaded "on demand" (e.g., column type classes). But if you load all your own Rose::DB::*-derived modules in startup.pl, that should cause all of the required classes to be loaded as each of your classes adds columns and so on. > c- this seems to save ~3mb of shared memory over just "use Rose::DB" You should really use your classes where possible. Since those classes "use base Rose::*", they will load the Rose::* modules they need. > creating a rose db object class and using it , adds about 9mb. > this adds about 12mb to apache (!). RDBO does "create once and then cache" a bunch of derived metadata. I plan to add some sort of "compile all" method or option to do all of this up-front rather than waiting for the first use. This should increase shared memory in a mod_perl environment.
