Does "load" mean "download"? If so, then ASCII is usually larger than bytecode.


There may be other issues too though, because HTML usually needs to fully

download before the page displays. SWF streams can often start playback and

execution quicker.


Java often has a lengthy startup... could be fast if someone already used

Java that session, could take a moment if they haven't.


If you're instead measuring execution speed, then it wouldn't be JavaScript

vs VBScript vs ActionScript, but rather JavaScript Interpreter A against

JSI B vs various VBScript interpreters and so on... the various browsers

have various script interpreters, and they can differ radically on even the

same stream of text-based instructions.


I'd go with Damien, and urge zooming down to the thing that actually needs

testing.



For "Which page can download over a modem and start interactions quicker?"

then a plain HTML page is usually the quickest (no scripts, no images, no

lengthy tables, etc)... if a SWF is embedded within that page that it can

start playing very quickly after that, depending on the authoring

techniques used... if you have more than a few images in an HTML page then

they'll load in sequence and browsers differ in when they may start... a

very complex piece of JavaScript or VBScript, beyond having browser

dependencies, can often exceed the size of a SWF. A lot depends on the

given task, sorry.
