One more thing... in your tests, you may want to save the
httpserver.log. If you still have problems, it will be useful to
compare cherokee logs vs httpserver logs.

Hi Thadeus,
I looked at the code you used for comparing web2py and Flask.
This is NOT A FAIR COMPARISON
Here is why:
1) you did not set migrate=False in web2py. This means at every
request you lock the entire database table metadata to check whether
the table has migrated. You do this
One more thing because of design flask with generate and reuse pyc
file. In the case of web2py python code is executed. You have to
explicitly bytecode compile via admin. I am not sure if you have
done that.

I will make said changes, and add my Flask-DAL extension to the flask app,
so at least the database layer will be the exact same.
Flask handles sessions too. I shouldn't disable web2py sessions while
letting flask use sessions, that would be an unfair test too.
The good news is, that even with
Thank you Thadeus for your help with these tests.
I did not see a open_session(request) in your Flask code.
Where does Flask save sessions? filesystem or client? If they are
saved on the client that is closer to session.forget() in web2py since

on web2py.com running with the recommended configuration (apache

from the logs and requests for static files served directly by
apache).
I was just about to create new topic, but thought I'd start by
reporting here since it could be related.

2. Open a page from my app on another laptop.
3. Also open the same page on the server
I am wondering if this is a web2py issue or a DAL issue.
I would like to re-run my tests just rendering a simple template with no

nothing else quite like it, and would hate for it to be the cause.

I have experienced a similar issue with web2py. Issue:
