Thanks for the detailed info. I have compressed my javascript using the Google Closure compiler. The process has been very slow (20 min?), and the resulting javascript could not start-up. I am not sure what went wrong. I will take another go at this at the end of the week. The compression factor was around 50%. I will post detailed metrics once I get this working.
