In https://gist.github.com/1410125#file_recentloginhistory.jsp line 43 should be >>> console.log(memberhistorymap); // notice the singular memberhist...
rest ooks file in that snippet. It would also be helpful to see the output of the different console.of output.

In https://gist.github.com/1410125#file_recent_login_history_action.java how did you verify that the json string is taking long time? I dont see you initializing the timeStart just before the "toJson" method is called. Can you give me the output of the time it takes to get to the toJson method & the time it takes after that point un till after you have set the value of "jsonString".
