because it does not tell anything about flash vs html. It's just a statement from a flashdeveloper that is speaking about e.g. performance and showing cpu usage. It would be great if flashdeveloper would read Tinic Uro's Blog and understand boundaries on systems and browser.
The performance of a flash animation/website also depends on how it was done. I've seen "BLING BLING" made by a flashdeveloper that uses 90-100% CPU. The same "BLING BLING" running on the same machine/browser done by an other flashdeveloper uses around 50% CPU ... Bla bla and no standardized tests.
