[lxml-dev] [objectify] optimization issues

[Stefan Behnel]

Hi Holger,

first of all: please create a new thread for a new topic instead of responding
to an existing message. Most mail client honour the "in reply to" hint in the
header and sort them into the old thread.

Then: what you observe are most likely GC 'issues'. The thing is: if the
element already exists as Python object, it is reused, which is much faster
then creating a new one. So in the cases where your code runs faster, you can
assume that the object survived a larger portion of your code without being
re-instantiated.

Especially recursive printing instantiates the entire tree, so if the objects
are not deleted directly afterwards, this has a performance effect on code
that runs afterwards.
