[web2py] Re: Performance Considerations

[Ross Peoples]

I think the sessions are locked while a controller is running using the same 
session. So it would slow down concurrent requests via AJAX and things like 
that, but that's why you need to call session.forget(request). Massimo's 
tips will certainly help, but I didn't know if there were any known 
bottlenecks in web2py itself that I might be able to help solve.
