I sent you the details via email. Elsewhere, someone has said java load times average to 525ms. I don't know how many servers compose the appengine "cloud," but whatever server I'm on sure doesn't respond with that speed.
I would be interested to know if there was a problem with the server I was on, or whether other people see their java apps getting killed after 10 seconds for "waiting too long."
