I have a fairly static page containing many widgets (100+). I've done
all I can to cache widget instantiation so that no widgets are
actually instantiated (unless a particular cached widget has become
stale) during the page call. This shaved about 3 seconds off of 9
second page load.
The expose(template="page") decorator around my method is still taking
a long time. The perpetrator appears to be Kid. Here is the profile
output showing it:

The following works for caching the entire page contents but what I
really need to do is cache only portions of the page to allow for
parts to change quickly.
@expose(template="page")
def _page(self, **kw):
val = self.alterSomething(kw)
return dict(wdgt=self.wdgt, value=val)
cache = None
@expose()
def page(self, **kw):
if self.cache is None or self.requiresChange(kw):
self.cache = self._page(**kw)
return self.cache
Caching individual segments of the page will require a lot more
complexity. Is there a way to make Kid go faster? I can't use psyco
because I'm running on an x86_64 machine. I even tried to hack
cElementTree back into Kid (it was taken out for some reason:
http://kid-templating.org/notes.html#celementtree-support)
Or have I reached the limits of TurboGears and this is why there's
support for other templating engines? And I just really got to like
the TG widget system...
Thanks,
Brian
