I am confused now, in your earlier reply you said
'Web applications must be written without persistent objects. State
is
share using the database, using sessions and using cache. '
and explained why other kinds of persistence were not possible. So are
global variables in modules as good
As Anthony suggests you can move code to modules and import modules.
Module can have global level variables (that do not depend on the user
or the request) that will be persistant within the process that
imports the module.
Database connections anyway, are handled by web2py in an efficient way

If you need distributed caching look at http://memcached.org/.

Only the stuff in models, and you can reduce that by using c
Hi Massimo,
In the first post of this thread, Arturo said,
"Is there a way in web2py to have varibles be persistent. For example
when I instantiate a class I don't want to re-instantiate it every
time a page is loaded."
I guess what he concerns is performance. In other word, "web2py re-

this is not a web2py issue. This is an issue for all web applications.
What if your application is replicated on two server behing a load
balancer? The two servers cannot share objects. What if you use a web

You have persistent connections: just use the pool: it is documented in the
book.
If you find problems with speed use the profiler that comes with web2py and
post here or open a ticket with the results and a model to reproduce those
problems, they will be fixed.

Excuse me Massimo,
but, if i understand well this answer, there is no way to have also a
persistent connection to the database or a global application variable
in web2py?
for every request the
You must use cache.ram but this is not guaranteed to work.
In a multi-threaded environment the web server decides which threads
to start/stop/kill.
