Subject [jira] [Commented] (FLEX-23466) Very Simple Proposal to Speed Up Download Times and Perceived Performance of Flex Apps
Date Sat, 04 May 2013 01:25:13 GMT

    [ https://issues.apache.org/jira/browse/FLEX-23466?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13648975#comment-13648975

Justin Mclean commented on FLEX-23466:

Interesting enough this was added (caching framework RSLs) and then taken away with the donation
to Apache Flex. As framework RSL caching is a Flash Player feature there noting Apache Flex
can do about this issue. (Sadly).

> I have been spending months trying to optimize some of our Flex apps, using all the standards
out there (RSL, Modules, externalizing assets, making code smaller too, etc.). RSLs don't
really work for most of my audience because because many of them have older computers and
it can take 10-20 seconds+ to download. 
> I was thinking, with the great advancement/feature of being able to cache Adobe frameworks
into the Flash Player, how about the idea of creating a base "wrapper" or "preloader" application
that was just a spark.components.Application, which is 300kb+, and somehow standardizing that.

> My thinking is that, if Adobe sponsors such a thing, and many people use it, we have
a much higher chance of that being cached in the browser from someone else so we can use it.
And it's small enough so the browser cache wouldn't mind that much. 
> Even better, what if you could cache a swf like that in the Flash Player! 
> Then all of our apps would effectively start out out 40kb (a module's size?). Loading
all the RSLs can be up to 2mb! With this, it'd be a lot smaller, and very practical. 
> Love to know your thoughts,
