Single Servlet Controller vs. Multiple Servlet Controllers

[maneesh subherwal]

All,
I have a question that folks here at JavaRanch may be familiar.
Using Tomcat's Specifications and the MVC pattern, is it better to use a single servlet controller or several servlets, one for each action, for a large application, in terms of container overhead and/or maintenance?
I believe I am using a SingleThreadModel for my servlets.
e.g.
SingleControllerServlet?UpdateDB
SingleControllerServlet?RetrieveFromDB
OR
UpdateDBServlet
RetrieveFromDBServlet
In case 1, I send the function as part of the queryString while in case 2, each servlet performs its own function and has less logic processing to do.
Thank you.

I have not much experience with developing model 2 apps since my main app was a kludge of different things. I recently came to re-do the application and I decided to got for the model 2 architecture for obvious reasons. After some brief development using a single controller it became a bit of a mess with tonnes of if/else statements.
I have now decided to go with a proven technology and use the Struts framework as a controller. This way all the mappings can be done in an XML file and thus the obvious advantage of leaving the code alone. Of course the disadvantage at the moment is that I have to learn Struts API but its not too complex and learning new things can not be a bad thing.
I hope this answer helps, your question is one of great importance and I would get advice from the main Servlets forum as a lot more are likely to contribute to it, as this forum is specific for those preparing for the exam.
I'll stop typing now.

It turns out this was also cross-posted in the Servlets forum, so I'm closing it here.
