Naveed, I've used both and my take is ... Since Catalyst is meant to be used for large web apps, the scaffolding tool builds a better foundation with good emphasis on MVC, how you should the components and where to place them. Since the latest runs on Plack as does most everything else, there is no real performance difference. In-Short .. the MVC-ness of Catalyst is the only benefit I can think of. I hate when people throw the term "scale" or "web-scale" around ... WTF does that mean? ... its vague enough that it could refer to any number of factors. Most good object-oriented code will "scale" as that its purpose .. other factors such as platform, database, web server, etc (and their respective scalability) have nothing to do with the frameworks scalability.

Dancer provides a thin layer above PSGI and abstraction for some of the work a user would have to do manually (sessions, templating, finding out what type of HTTP method it is, setting the content type, etc.). You (or rather, Dancer, if that's what you're using) provide PSGI with an app handler subroutine. For example: sub app { my $env = shift; return [ '200', [ 'Content-Type' => 'text/plain' ], [ "Hello World" ], # or IO::Handle-like object

];

} How many people would do that? Very few.

True! However, I'd be interested in seeing how many people are writing their own Plack::Middleware components. As it's a nice and easy way to replace a lot of work you normally might be forced to write with mod_perl handlers, I would expect that the use of custom Middleware should rise over time as well.

Good idea!

That would be an interesting/useful metric.
