If one was to start Zope with python -O, then it would look for (and
generate) .pyo files instead of .pyc's in all the Products right?
Would there be any performance gain by this change? How much?
Is it worth me doing byte-compiles with -O and starting Zope's
interpreter in this mode?
There is no anachronism at all. Building Python by hand will also
build .pyo files alonside .pyc files. There is a speed increase
running Zope with .pyos, but if I remember correctly you have to hack
one of the startup files to correctly pass all python flags given
upon startup. I don't know anyone who has done specific testing to
quantify the speed increase, though.
There is a drawback: Debugging becomes a lot harder and sometimes
impossible because you get no or faulty line number information in
tracebacks and when using pdb.
