Update:

sjcl does have this issue (see attached), and it does not occur in FireFox 17 
suggesting it's an issue with Chrome 25 and not with either library.

Google's description for dev releases of Chrome says that it's "where ideas get 
tested (and sometimes fail); the Dev channel can be very unstable at times." So 
I don't think we need to worry too much about CryptoJS's results when tested on 
an unstable dev build.

I can, however, confirm the speed difference in the latest stable Chrome. I'll 
investigate where that performance comes from.

Changing label from defect to enhancement since the bug report is invalid 
(browser bug in unstable build) but the performance comparison is a valid 
enhancement request.
