You talk about performance, but I think that is another point for PHP. In my experience, PHP handles the same requests faster.

Yes, I could build everything from scratch myself in Python and have the same statelessnes as in PHP. But parsing headers, creating headers etc feels like it should be handled by a framework. In PHP, it is build right in.

And if I would build it, it would talk to the webserver via CGI. But I think CGI is slow. For PHP, you have mod-php which is super fast.
