A light(er)weight twitter feed widget?

I'm making use of the "official" twitter feed widget, and also I simply saw in Firefox is network assessor that it is including+- 220 kB of information to my website at load time. 100 kB is the "widgets.js" documents, the various other 100 kB is a json documents (which strangely sufficient is just 9kB when I replicate the URL and also download it from the address bar??).

Any kind of pointer for lowering those documents dimensions? In addition to personalized coding a RSS feed extractor thingy which would not rely on their widgets.js?

I'm simply attempting to skim some fat for faster load times
