-------------------------------+--------------------------------------------
There is a potential problem with mako template caching the way it is used
by TG2. If you expose a controller method and decorate it with mako
template it gets served 2 or 3 times slower than when you expose a "raw"
method which uses mako.lookup.TemplateLookup to rended template directly.
For example:
{{{
class MyController(object)
@expose('mako:proj.templates.mako_speed')
def automatic(self):
return dict()
}}}
is 3 times slower than
{{{
from mako.template import Template
from mako.lookup import TemplateLookup
templates = '...full path...'
mylookup = TemplateLookup(
directories=[templates],
# same difference with and without next line:
#module_directory=templates,
output_encoding='utf-8')
def serve_template(templatename, **kwargs):
mytemplate = mylookup.get_template(templatename)
return mytemplate.render(**kwargs)
class MyController(object)
@expose()
def manual(self):
return serve_template('mako_speed.mak')
}}}
There is an example attached to this ticket. Put mako_speed.mak into your
templates directory, and mako_speed.py into controllers directory. Expose
MakoSpeedController as "mako_speed" in your root controller.
