Thank you all for remembering me this! I used Catalyst::Model::Factory
somewhere else exactly because it doesn't create just a single object
instance like C::M::Adaptor, but I have forgotten.

Well, it is not exactly without numbers. I have tried
ab -n 200 -c 5 http://localhost/
The result was... 3 to 4 requests per second.
I commented the line that stores the menu in the stash (for not using the
menu at all) and the same command line gave a result of around 33 requests
per second, which is a very big difference.
So I think the buggy part is the module that creates the menu object from
the data structure loaded in the configuration file.
I will first try to use the data structure directly in the TT template
without creating an object from it.
If it would be too slow, I will try to "draw" the menu entirely in the
template without using an external data structure, although I don't like
Thank you all very much for your help.
