javascript - JS compression - PageSpeed (Google Chrome report) -

i'm running pagespeed google chrome extension check performance of webpage. believe have got compressed js file (see attached code) report says can compressed again 59% reduction. missing here?

update: using play framework. can done using require.js optimizer?
