The current prototype.js is about 130kb, on a high performance site
this is quite a lot. Does anyone have an idea how I can only use the
Ajax portion of prototype.js so the .js file gets smaller?

Thanks,

Otherwise, you can just configure your web server to GZip it (~30KB) and
set a long cache expiry to it, that does nicely as well.

I totally agree with gzipping.
Minified and gzipped Prototype is 20.7kb.

Currently YUI Compressor is compatible with Prototype 1.6.0.2 and its
use of the $super variable.
I have also modified a version of Dean Edwards packer 3 to support the
$super variable.
