Framework caching is potentially a useful way to reduce the download required for each flex application. It doesn't benefit the user if there are not many sites using it as the total download of the flex app + framework as a seperate file is greater.
I am working on some integration for a public site with a large Flex element, in an experiment with our app a normal Flex release build totalled 673k without framework caching and 426k with framework caching. This is all very good, but the framework as an swf for earlier Flash 9 player () users is 523k, that means the total download for a user without the framework cached is 949k. This is 230k more than if the framework cache is not enabled. Although it is good to help everybody out by using caching I would like to know what proportion of users will benefit and therefore what proportion of sites have implemented Framework caching. Does anyone have a figure on this? Thanks
