javascript bootloader

So i've built a javascript bootloader to dynamically load JS files as they are needed and to call a loaded function after the load is complete. I've read facebook does this, and it has dramatically sped up their pages b/c they only load the exact JS they need. I guess you havta be using like 500 KB of JS for this to be useful, but it seems like it could to useful to smaller sites as well, seeing as though my bootloader script is only 900 Bytes.

 

Thoughts?

I used to use dynamically loading js, but it ended up being allot more efficient to put all js into one file and the minify it.

 

Its the actual http requests to multiple files that hurts more than size. Of course it would also depend on what sizes where talking about. Loading a 50k-80k file just to use one function etc etc.
