Hey guys,
I've got a question about how Zope deals with shared libraries. Say I have a 2Meg shared library that I've generated with SWIG. (I know it's big, but for sake of argument) Say then that I create a Python Class that imports this library and provides a front-end for each of its exported methods. Then, I instantiate this class 2000 times within a Zope instance. My question is, the library code is loaded into memory once, right?
Right. In fact, if you were running multiple Zope (or Python) processes using the library, then there would only be one copy in memory shared among the multiple processes.
That seems to be what should happen, but I want to make sure before I start selling people here on SWIGing a few utilities and bundling them into one of our Zope objects instead of doing fork/execs to call an executable. I'm not shifting the burden from loading time to storage size, am I?
