Well, as far as I know, "bytecode" is generated by the marshal module. And marshal can only precompile simple data types and code (classes, functions). So objects (class instances) can not be byte compiled. But I may be wrong... However, I had a funny idea too... I have been wondering about using marshal in ZODB instead of pickle, I mean, we only store object's states there, and as far as I have been investigating object states are simple python types that could be handled by marshal... But I am pretty sure I may have missed something that makes this completely impossible to achieve. It's just that, even using the highest protocol in pickle, serialization and deserialization of simple python types is much faster with marshal.

Dear zope core developers, I have idea about bytecode cache in Zope, it is possible to implement? What I mean: python scripts (in ZODB), DTML documents/methods, ZPT will be bytecode compiled in similar way like ordinary .py scripts into .pyc and then run much faster than "noncompiled" ZODB objects. I think that it should have significant speed improvement. ... or I am totally out?
