Viewstates and postbacks are entirely within the control of the programmer. They can be controlled at Page or control level. Plus with Ajax support (and what fantastic support it is!) it is unrecognisable as the same system that you are describing. Can't agree with your comments, I'm afraid.

This is surprising as tests have shown that PHP compiled under .NET generally runs twice as fast as under Zend (http://www.codeproject.com/KB/cross-platform/phalanger-intro.aspx) There are lots of gotchas under asp.net and bad programming can contribute to slow performance. Generally ASP.NET pages with the viwstate enabled will be bigger than an equivalent page in PHP. Although the viewstate makes possible the really squiffy programming interface it needs to be used with care. So, although .NET should be faster, bad programming is probably responsible for a lot of slow sites.
